Moreover, that we might understand that he was not included in this federal transaction with Adam, the apostle opposes him, as the _second Man_, the federal Head of his elect, or spiritual seed, to Adam, the _first man_, and head of his natural seed, in that scripture before referred to, ver. 45. And, as an argument, that his extraordinary and miraculous conception exempted him from any concern in Adam’s sin and fall; the angel, that gave the first intimation hereof, when he tells the blessed virgin, his mother, that _the Holy Ghost should come upon her, that the power of the highest should over-shadow her_, he says, _Therefore that Holy Thing, that shall be born of thee, shall be called, the Son of God_; thereby implies, that, in his first formation, he was holy, and consequently had no concern in the guilt of Adam’s sin, because of the manner of his formation, or conception; and this is certainly a better way to account for his being sinless, than to pretend, as the Papists do, that his mother was sinless; which will do no service to their cause, unless they could ascend in a line to our first parents, and so prove, that all our Saviour’s progenitors were immaculate, as well as the virgin; which is more than they pretend to do. III. It is farther observed, in this answer, that mankind sinned in and fell with Adam in his _first transgression_, and therefore they had no concern in those sins, which he committed afterwards. This appears from hence, that Adam, as soon as he sinned, lost the honour and prerogative, that was conferred upon him, of being the federal head of his posterity, though he was their natural head, or common father; for the covenant being broken, all the evils, that we were liable to, arising from thence, were devolved upon us, and none of the blessings, contained therein, could be conveyed to us that way, since it was impossible for him, after his fall, to perform sinless obedience, which was the condition of the life promised therein. This doth not arise so much from the nature of the covenant, as from the change that there was in man, with whom it was made. The law, or covenant, would have given life, if man could have yielded perfect obedience; but since his fall rendered that impossible, though the obligation thereof, as a law, distinct from a covenant, and the curse, arising from the sanction thereof, remains still in force against fallen man; yet, as a covenant, in which life was promised, it was, from that time, abrogated; and therefore the apostle speaks of it, as being _weak through the flesh_, Rom. viii. 3. that is, by reason of Adam’s transgression, and consequently he ceased, from that time, to be the federal head, or means of conveying life to his posterity; therefore those sins that he committed afterwards, were no more imputed to them, to inhance their condemnation, than his repentance, or good works, were imputed for their justification.
