And it is worthy our particular observation here that, after the sin of the fall, no further law whatever was imposed on Adam, though nature in its state of perfection had a divine law set before it. The reason of this was, because God saw that nature, being now fallen and corrupt, could not only derive no help or relief from any law given to it, but that, being thus corrupted and also disorganized and confused altogether, it could not bear any syllable of law whatsoever. Wherefore God did not increasedly oppress nature, already thus oppressed by sin, with any further law of any kind. But on the contrary God mercifully applied unto sin as a terrible wound, a healing plaster, that is, the promise concerning Christ, still using that caustic, the curse on sin, which the devil had caused to be inflicted. For as wholesome plasters, even while they heal, yet corrode and pain the flesh; so the healing promise is so set before Adam that the threatened curse on sin should be added, to operate with it in curing the lust of the flesh. By the lust of the flesh I mean, not only that foul motion and itching of lust, but also "all manner of concupiscence" and uncleanness of soul, as Paul terms them, Rom. 7:8; Eph. 4:19, through which we are by nature inclined to idolatry, unbelief, self-security and all other horrible sins against the first and second Table. To curb and cure all this depravity of nature, we have need of the operation of this burning caustic, the curse of God on sin. I would that I could handle the text now before us in a manner becoming its depth and dignity, for it embraces all that is glorious in the whole Scripture, containing in it the curse of God on Satan and the destruction of the seed of the serpent by the seed of the woman. The former part of the text is wholly figurative. God speaks to the serpent, but it is manifest that the serpent alone is not here to be understood as addressed by God. For these are not the words of God as a Creator, as were those words above, when he said unto the beasts of the earth, "Be fruitful and multiply;" nor when he said to the earth itself, "Let the earth bring forth grass, and herbs, and trees, yielding seed after their kind." They are words of divine threatening and a declaration of mind and will, such words as God never speaks to an irrational creature, but to an intelligent creature only.
