And if it be objected hereunto, that she could not then be the mother of innocent children, for _who can bring a clean thing out of an unclean?_ The reply, which is usually given to this, which is only matter of conjecture, is, that God would have created some other woman, who should have been the mother of a sinless posterity.[56] The reason why these conclude that the covenant was made only with Adam, is because we never read expressly, in scripture, of its being made with Eve in behalf of her posterity; and particularly it is said, in Gen. ii. 16, 17. that _the Lord God commanded the man, saying, Of every tree in the garden thou mayest freely eat; but of the tree of knowledge of good and evil, thou shalt not eat of it; for in the day thou eatest thereof, thou shalt surely die_. And it is observed, that this law was given to him before the woman was created; for it said, in the following words, _It is not good that man should be alone; I will make him an help meet for him_. And, in other scriptures, which treat of this matter, we read of the man’s being the head of the covenant, but not his wife: thus the apostle, in 1 Cor. xv. 45, 47. compares him, whom he styles, _the first man, Adam_, as the head of this covenant, with Christ, whom he calls, _The second man_, as the head of the covenant of grace; and elsewhere he says, _As in Adam all die, so in Christ shall all be made alive_, ver. 22. and again _By one man sin entered into the world_, &c. Rom. v. 12. and _By one man’s disobedience, many were made sinners_, ver. 19. It is not said by the disobedience of our first parents, but of one of them, to wit, Adam; therefore, from hence, they conclude, that he only was the head of this covenant, and herein the representative of mankind.
