The reader of this perennially fresh story is first of all struck with the account given of man's primitive condition. Coming to this narrative with our minds coloured by the fancies of poets and philosophers, we are almost startled by the check which the plain and sober statements of this account give to an unpruned fancy. We have to read the words again and again to make sure we have not omitted something which gives support to those glowing descriptions of man's primitive condition. Certainly he is described as innocent and at peace with God, and in this respect no terms can exaggerate his happiness. But in other respects the language of the Bible is surprisingly moderate. Man is represented as living on fruit, and as going unclothed, and, so far as appears, without any artificial shelter either from the heat of the sun or the cold of night. None of the arts were as yet known. All working of metals had yet to be discovered, so that his tools must have been of the rudest possible description; and the arts, such as music, which adorn life and make leisure enjoyable, were also still in the future.
But the most significant elements in man's primitive condition are represented by the two trees of the garden; by trees, because with plants alone he had to do. In the centre of the garden stood the tree of life, the fruit of which bestowed immortality. Man was therefore naturally mortal, though apparently with a capacity for immortality. How this capacity would have actually carried man on to immortality had he not sinned, it is vain to conjecture. The mystical nature of the tree of life is fully recognised in the New Testament, by our Lord, when He says: "To him that overcometh will I give to eat of the tree of life, which is in the midst of the Paradise of God;" and by John, when he describes the new Jerusalem: "In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations." Both these representations are intended to convey, in a striking and pictorial form, the promise of life everlasting.
And as of the tree of life which stands in the Paradise of the future it is said "Blessed are they that do His commandments, that they may have right to the tree of life;" so in Eden man's immortality was suspended on the condition of obedience. And the trial of man's obedience is imaged in the other tree, the tree of the knowledge of good and evil. From the child-like innocence in which man originally was, he was to pass forward into the condition of moral manhood, which consists not in mere innocence, but in innocence maintained in presence of temptation. The savage is innocent of many of the crimes of civilized men because he has no opportunity to commit them; the child is innocent of some of the vices of manhood because he has no temptation to them. But this innocence is the result of circumstance, not of character; and if savage or child is to become a mature moral being he must be tried by altered circumstances, by temptation and opportunity. To carry man forward to this higher stage trial is necessary, and this trial is indicated by the tree of knowledge. The fruit of this tree is prohibited, to indicate that it is only in presence of what is forbidden man can be morally tested, and that it is only by self-command and obedience to law, and not by the mere following of instincts, that man can attain to moral maturity. The prohibition is that which makes him recognise a distinction between good and evil. He is put in a position in which good is not the only thing he can do; an alternative is present to his mind, and the choice of good in preference to evil is made possible to him. In presence of this tree child-like innocence was no longer possible. The self-determination of manhood was constantly required. Conscience, hitherto latent, was now evoked and took its place as man's supreme faculty.
