The Fall
The man, whom God had appointed lord of the earth and its inhabitants, was endowed with everything requisite for the development of his nature and the fulfilment of his destiny. In the fruit of the trees of the garden he had food for the sustenance of his life; in the care of the garden itself, a field of labour for the exercise of his physical strength; in the animal and vegetable kingdom, a capacious region for the expansion of his intellect; in the tree of knowledge, a positive law for the training of his moral nature; and in the woman associated with him, a suitable companion and help. In such circumstances as these he might have developed both his physical and spiritual nature in accordance with the will of God. But a tempter approached him from the midst of the animal world, and he yielded to the temptation to break the command of God. The serpent is said to have been the tempter. But to any one who reads the narrative carefully in connection with the previous history of the creation, and bears in mind that man is there described as exalted far above all the rest of the animal world, not only by the fact of his having been created in the image of God and invested with dominion over all the creatures of the earth, but also because God breathed into him the breath of life, and no help meet for him was found among the beasts of the field, and also that this superiority was manifest in the gift of speech, which enabled him to give names to all the rest - a thing which they, as speechless, were unable to perform, - it must be at once apparent that it was not from the serpent, as a sagacious and crafty animal, that the temptation proceeded, but that the serpent was simply the tool of that evil spirit, who is met with in the further course of the world's history under the name of Satan (the opponent), or the Devil (ὁ διάβολος, the slanderer or accuser).
(Note: There was a fall, therefore, in the higher spiritual world before the fall of man; and this is not only plainly taught in 2-Peter 2:4 and Jde 1:6, but assumed in everything that the Scriptures say of Satan. But this event in the world of spirits neither compels us to place the fall of Satan before the six days' work of creation, nor to assume that the days represent long periods. For as man did not continue long in communion with God, so the angel-prince may have rebelled against God shortly after his creation, and not only have involved a host of angels in his apostasy and fall, but have proceeded immediately to tempt the men, who were created in the image of God, to abuse their liberty by transgressing the divine command.)
When the serpent, therefore, is introduced as speaking, and that just as if it had been entrusted with the thoughts of God Himself, the speaking must have emanated, not from the serpent, but from a superior spirit, which had taken possession of the serpent for the sake of seducing man. This fact, indeed, is not distinctly stated in the canonical books of the Old Testament; but that is simply for the same educational reason which led Moses to transcribe the account exactly as it had been handed down, in the pure objective form of an outward and visible occurrence, and without any allusion to the causality which underlay the external phenomenon, viz., not so much to oppose the tendency of contemporaries to heathen superstition and habits of intercourse with the kingdom of demons, as to avoid encouraging the disposition to transfer the blame to the evil spirit which tempted man, and thus reduce sin to a mere act of weakness. But we find the fact distinctly alluded to in the book of Wis. 2:24; and not only is it constantly noticed in the rabbinical writings, where the prince of the evil spirits is called the old serpent, or the serpent, with evident reference to this account, but it was introduced at a very early period into Parsism also. It is also attested by Christ and His apostles (John 8:44; 2-Corinthians 11:3 and 2-Corinthians 11:14; Romans 16:20; Revelation 12:9; Revelation 20:2), and confirmed by the temptation of our Lord. The temptation of Christ is the counterpart of that of Adam. Christ was tempted by the devil, not only like Adam, but because Adam had been tempted and overcome, in order that by overcoming the tempter He might wrest from the devil that dominion over the whole race which he had secured by his victory over the first human pair. The tempter approached the Saviour openly; to the first man he came in disguise. The serpent is not a merely symbolical term applied to Satan; nor was it only the form which Satan assumed; but it was a real serpent, perverted by Satan to be the instrument of his temptation (Genesis 3:1 and Genesis 3:14). The possibility of such a perversion, or of the evil spirit using an animal for his own purposes, is not to be explained merely on the ground of the supremacy of spirit over nature, but also from the connection established in the creation itself between heaven and earth; and still more, from the position originally assigned by the Creator to the spirits of heaven in relation to the creatures of earth. The origin, force, and limits of this relation it is impossible to determine a priori, or in any other way than from such hints as are given in the Scriptures; so that there is no reasonable ground for disputing the possibility of such an influence. Notwithstanding his self-willed opposition to God, Satan is still a creature of God, and was created a good spirit; although, in proud self-exaltation, he abused the freedom essential to the nature of a superior spirit to purposes of rebellion against his Maker. He cannot therefore entirely shake off his dependence upon God. And this dependence may possibly explain the reason, why he did not come "disguised as an angel of light" to tempt our first parents to disobedience, but was obliged to seek the instrument of his wickedness among the beasts of the field. The trial of our first progenitors was ordained by God, because probation was essential to their spiritual development and self-determination. But as He did not desire that they should be tempted to their fall, He would not suffer Satan to tempt them in a way which should surpass their human capacity. The tempted might therefore have resisted the tempter. If, instead of approaching them in the form of a celestial being, in the likeness of God, he came in that of a creature, not only far inferior to God, but far below themselves, they could have no excuse for allowing a mere animal to persuade them to break the commandment of God. For they had been made to have dominion over the beasts, and not to take their own law from them. Moreover, the fact that an evil spirit was approaching them in the serpent, could hardly be concealed from them. Its speaking alone must have suggested that; for Adam had already become acquainted with the nature of the beasts, and had not found one among them resembling himself - not one, therefore, endowed with reason and speech. The substance of the address, too, was enough to prove that it was no good spirit which spake through the serpent, but one at enmity with God. Hence, when they paid attention to what he said, they were altogether without excuse.
