It is plain that the temptation under which man fell in paradise was this, an ambitious curiosity after knowledge which was not allowed him:  next came the desire of the eyes and the flesh, but the forbidden tree was called the tree of knowledge; the Tempter promised knowledge; and after the fall Almighty God pronounced, as in the text, that man had gained it.  “Behold, the man is become as one of Us, to know good and evil.”

You see it is said, “man is become as one of Us, to know good and evil,” because God does know evil as well as good.  This is His wonderful incommunicable attribute; and man sought to share in what God was, but he could not without ceasing to be what God was also, holy and perfect.  It is the incommunicable attribute of God to know evil without experiencing it.  But man, when he would be as God, could only attain the shadow of a likeness which as yet he had not, by losing the substance which he had already.  He shared in God’s knowledge by losing His image.  God knows evil and is pure from it man plunged into evil and so knew it.

Our happiness as well as duty lies in not going beyond our measure in being contented with what we are with what God makes us.  They who seek after forbidden knowledge, of whatever kind, will find they have lost their place in the scale of beings in so doing, and are cast out of the great circle of God’s family.

It is, I say, God’s incommunicable attribute, as He did not create, so not to experience sin and as He permits it, so also to know it; to permit it without creating it, to know it without experiencing it a wonderful and incomprehensible attribute truly, yet involved, perhaps, in the very circumstance that He permits it.  For He is every where and in all, and nothing exists except in and through Him.  Mysterious as it is, the very prison beneath the earth, its chains and fires and impenitent inmates, the very author of evil himself, is sustained in existence by God, and without God would fall into nothing.  God is in hell as well as in heaven, a thought which almost distracts the mind to think of.  The awful God!  “Whither shall I go from Thy Spirit, or whither shall I go from Thy Presence?  If I climb up into heaven, Thou art there; if I go down to hell, Thou art there also.”  Where life is, there is He; and though it be but the life of death the living death of eternal torment He is the principle of it.  And being thus intimately present with the very springs of thought, and the first elements of all being, being the sustaining cause of all spirits, whether they be good or evil, He is intimately present with evil, being pure from it and knows what it is, as being with and in the wretched atoms which originate it.

If there be this sort of connexion between God’s knowledge and sufferance of evil, see what an ambition it was in our first parents to desire to know it without experiencing it; it was, indeed, to desire to be as gods, to know the secrets of the prison-house, and to see the worm that dieth not, yet remain innocent and happy.

This they understood not; they desired something which they knew not that they could not have, remaining as they were; they did not see how knowledge and experience went together in the case of human nature; and Satan did not undeceive them.  They ate of the tree which was to make them wise, and, alas! they saw clearly what sin was, what shame, what death, what hell, what despair.  They lost God’s presence, and they gained the knowledge of evil.  They lost Eden, and they gained a conscience.

This, in fact, is the knowledge of good and evil.  Lost spirits do not know good.  Angels do not know evil.  Beings like ourselves, fallen beings, fallen yet not cast away, know good and evil; evil not external to them, nor yet one with them; but in them, yet not simply of them.  Such was the fruit of the forbidden tree, as it remains in us to this day.

We do not know in what the duty and happiness of other beings consist; but at least this seems to have been man’s happiness in Paradise, not to think about himself or to be conscious of himself.  Such, too, to recur to the parallel especially suggested on this day, seems to be the state of children.  They do not reflect upon themselves.  Such, too, seems to be the state of those orders of Angels whose life is said to consist in contemplation for what is contemplation but a resting in the thought of God to the forgetfulness of self?  Hence the Saints are described as “Virgins who follow the Lamb whithersoever He goeth.”  But Adam, discontented with what he was, pined after a knowledge which he could not obtain from without which he could only have from miserable experience within from moral disorders within him, and from having his mind drawn to the contemplation of himself in consequence of those disorders.  He obtained the wished for knowledge; and his first recorded act afterwards was one of reflection upon self, and he hid himself among the trees of the garden.  He was no longer fitted for contemplating glories without him; his attention was arrested to the shame that was upon him.

What is so miserably seen in the history of our first parents has been the temptation and sin of their posterity ever since, indulgence in forbidden, unlawful, hurtful, unprofitable knowledge; as some instances will show.

1.  I ought to notice in the first place that evil curiosity which stimulates young persons to intrude into things of which it is their blessedness to be ignorant.  Satan gains our souls step by step; and his first allurement is the knowledge of what is wrong.  He first tempts them to the knowledge, and then to the commission of sin.  Depend on it that our happiness and our glory, in these matters, is to be ignorant, as well as to be guiltless.  St. Paul says that “it is a shame even to speak” of those things which are done by the sons of Belial in secret.  Oh, thoughtless, and worse, oh, cruel to your own selves, all ye who read what ye should not read, and hear what ye should not hear!  Oh, how will you repent of your folly afterwards!  Oh, what bitter feelings, oh, what keen pangs, will shoot through your souls hereafter, at the memory, when you look back, of what has come of that baneful curiosity!  Oh, how will you despise yourselves, oh, how weep at what you have brought on you!  At this day surely there is a special need of this warning; for this is a day when nothing is not pried into, nothing is not published, nothing is not laid before all men.

2.  In the next place I would observe, that the pursuit of science, which characterizes these times, is very likely to draw us aside into a sin of a particular kind, if we are not on our guard.  We read, in the book of Acts, of many who used curious arts burning their books; that is, there are kinds of knowledge which are forbidden to the Christian.  Now this seems strange to the world in this day.  The only forbidden subjects which they can fancy, are such as are not true fictions, impostures, superstitions, and the like.  Falsehood they think wrong; false religions, for instance, because false.  But they are perplexed when told that there may be branches of real knowledge, yet forbidden.  Yet it has ever been considered in the Church, as in Scripture, that soothsaying, consulting the stars, magic, and similar arts, are unlawful unlawful, even though not false; and Scripture certainly speaks as if at least some of them were more than merely a pretended knowledge and a pretended power; whereas men now-a-days have got to think that they are wrong, merely because frauds and impostures; and if they found them not so, they would be very slow to understand how still they are unlawful.  They have not mastered the idea that real knowledge may be forbidden us.

3.  Next it is obvious to speak of those melancholy persons who boast themselves on what they call their knowledge of the world and of life.  There are men, alas not a few, who look upon acquaintance with evil as if a part of their education.  Instead of shunning vice and sin, they try it, if for no other reason, simply for this that they may have knowledge of it.  They mix with various classes of men, and they throw themselves into the manners and opinions of all in turn.  They are ready-witted perhaps, prompt and versatile, and easily adapt themselves so as to please and get acquainted with those they fall in with.  They have no scruples of conscience hindering them from complying with whatever is proposed; they are of any form of religion, have lax or correct morals, according to the occasion.  They can revel with those that revel, and they can speak serious things when their society is serious.  They travel up and down the country perhaps, or they are of professions or pursuits which introduce them to men of various languages, or which take them abroad, and they see persons of opposite creeds and principles, and whatever they fall in with they take as so many facts, merely as facts of human nature, not as things right or wrong according to a certain fixed standard independent of themselves.  Now whatever of religion or truth remains in our fallen nature is not on the surface:  these men, then, studying what is uppermost, are in fact but studying all that is evil in man, and in consequence they have very low notions of man.  They are very sceptical about the existence of principle and virtue; they think all men equally swayed by worldly, selfish, or sensual motives, though some hide their motives better than others, or have feelings and likings of a more refined character.  And having given in to sin themselves, they have no higher principle within them to counteract the effect of what they see without; all their notions of man’s nature, capabilities, and destinies, are derived from, and are measured by, what goes on in the world, and accordingly they apply all their knowledge to bad purposes.  They think they know, and they do know too truly on the whole, the motives and inducements which will prevail with men; and they use their knowledge to overreach, deceive, seduce, corrupt, or sway those with whom they have to do.

4.  Another very different class of persons who study evil, and pride themselves upon it, and are degraded by it, are those who indulge themselves in contemplating and dwelling on the struggle between right and wrong in their own minds.  There have been from time to time men of morbid imaginations, of any or no religious creed, who have so exercised themselves.  Indeed there has been a large school of writers in very various departments, for years, I may say centuries past, though happily they are diminishing now, who delight in bringing out into open day all the weaknesses and inconsistencies of human nature; nay worse, take pains to describe bad men, and how they feel, and what they say; who interest the mind in bad men, nay in bad Angels, as if Satan might be thought of otherwise than with shuddering.  And there are others, men of mistaken religious views, who think that religion consists in dwelling on and describing the struggle between grace and corrupt nature in the soul.  Christ has brought us light and life, and would have us put off what we are, and follow Him, who knew no sin.  But these men, far from rising even to the aspiration after perfection, do not advance in their notion of spiritual religion beyond the idea of declaring and lamenting their want of it.  Confession is with them perfection; nay, it is almost the test of a Christian, to be able to discourse upon his inward corruption.  It is well to confess sin in detail with shame as an act of penitence; it is a snare to speak of it vaguely and in public.

5.  Lastly, even when used rightly, the knowledge of sin is not without its danger.  As mediciners would not exist were there no illness or disease, so it is mental disease which gives rise to casuists.  Pain leads us to think of our bodies, and sin of our souls.  Were our souls in perfect harmony, they would act like an instrument in tune; we should with difficulty divide the sounds, even if we would; but it is the discordance, the jar within us, which leads us to a serious contemplation of what we are.  The same remark obviously applies to a great deal of theological knowledge, on which men who have it are tempted to pride themselves; I mean exact knowledge of hérésies and the like.  The love of God alone can give such knowledge its right direction.  There is the danger lest men so informed find themselves scrutinizing when they should be adoring, reasoning when they should be believing, comparing when they should be choosing, and proving when they should be acting.  We know two things of the Angels that they cry Holy, Holy, Holy, and that they do God’s bidding.  Worship and service make up their blessedness; and such is our blessedness in proportion as we approach them.  But all exercises of mind which lead us to reflect upon and ascertain our state; to know what worship is, and why we worship; what service is, and why we serve; what our feelings imply, and what our words mean, tend to divert our minds from the one thing needful, unless we are practised and expert in using them.  All proofs of religion, evidences, proofs of particular doctrines, scripture proofs, and the like, these certainly furnish scope for the exercise of great and admirable powers of mind, and it would be fanatical to disparage or disown them; but it requires a mind rooted and grounded in love not to be dissipated by them.  As for truly religious minds, they, when so engaged, instead of mere disputing, are sure to turn inquiry into meditation, exhortation into worship, and argument into teaching.

Reflections such as these, followed up, show us how different is our state from that for which God made us.  He meant us to be simple, and we are unreal; He meant us to think no evil, and a thousand associations, bad, trifling, or unworthy, attend our every thought.  He meant us to be drawn on to the glories without us, and we are drawn back and (as it were) fascinated by the miseries within us.  And hence it is that the whole structure of society is so artificial; no one trusts another, if he can help it; safeguards, checks, and securities are ever sought after.  No one means exactly what he says, for our words have lost their natural meaning, and even an Angel could not use them naturally, for every mind being different from every other, they have no distinct meaning.  What, indeed, is the very function of society, as it is at present, but a rude attempt to cover the degradation of the fall, and to make men feel respect for themselves, and enjoy it in the eyes of others, without returning to God.  This is what we should especially guard against, because there is so much of it in the world.  I mean, not an abandonment of evil, not a sweeping away and cleansing out of the corruption which sin has bred within us, but a smoothing it over, an outside delicacy and polish, an ornamenting the surface of things while “within are dead men’s bones and all uncleanness;” making the garments, which at first were given for decency, a means of pride and vanity.  Men give good names to what is evil, they sanctify bad principles and feelings; and, knowing that there is vice and error, selfishness, pride, and ambition, in the world, they attempt, not to root out these evils, not to withstand these errors; that they think a dream, the dream of theorists who do not know the world; but to cherish and form alliance with them, to use them, to make a science of selfishness, to flatter and indulge error, and to bribe vice with the promise of bearing with it, so that it does but keep in the shade.

But let us, finding ourselves in the state in which we are, take those means which alone are really left us, which alone become us.  Adam, when he had sinned, and felt himself fallen, instead of honestly abandoning what he had become, would fain have hid himself.  He went a step further.  He did not give up what he now was, partly from dread of God, partly from dislike of what he had been.  He had learnt to love sin and to fear God’s justice.  But Christ has purchased for us what we lost in Adam, our garment of innocence.  He has bid us and enabled us to become as little children; He has purchased for us the grace of simplicity, which, though one of the highest, is very little thought about, is very little sought after.  We have, indeed, a general idea what love is, and hope, and faith, and truth, and purity, though a poor idea; but we are almost blind to what is one of the first elements of Christian perfection, that simple-mindedness which springs from the heart’s being whole with God, entire, undivided.  And those who think they have an idea of it, commonly rise no higher than to mistake for it a mere weakness and softness of mind, which is but its counterfeit.  To be simple is to be like the Apostles and first Christians.  Our Saviour says, “Be ye harmless,” or simple, “as doves.”  And St. Paul, “I would have you wise unto that which is good, and simple concerning evil.”  Again, “That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation.”  And he speaks of the “testimony of” his own “conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God,” he had his conversation in the world and towards his disciples.  Let us pray God to give us this great and precious gift; that we may blot out from our memory all that offends Him; unlearn all that knowledge which sin has taught us; rid ourselves of selfish motives, self-conceit, and vanity, littlenesses, envying, grudgings, meannesses; turn from all cowardly, low, miserable ways; and escape from servile fears, the fear of man, vague anxieties of conscience, and superstitions.  So that we may have the boldness and frankness of those who are as if they had no sin, from having been cleansed from it; the uncontaminated hearts, open countenances, and untroubled eyes of those who neither suspect, nor conceal, nor shun, nor are jealous; in a word, so that we may have confidence in Him, that we may stay on Him, and rest in the thoughts of Him, instead of plunging amid the thickets of this world; that we may bear His eye and His voice, and know no knowledge but the knowledge of Him and Jesus Christ crucified, and desire no objects but what He has blessed and bid us pursue.
