The resemblance, on account of which Adam is regarded as the type of Christ, consists in this, that Adam communicated to those whom he represented ( being their federal head ) what belonged to him, and that Christ also communicated to those whom He represents ( being the federal head of God's elect ) what belonged to Him. There is, however, a great dissimilarity between what the one and the other communicates By his disobedience Adam has communicated sin and death, and by His obedience Christ has communicated righteousness and life; and as Adam was the author of the natural life of his posterity, so Christ is the author of the spiritual life which His people now possess, and which they shall enjoy at their resurrection, so that, in accordance with these analogies, He is called the last Adam. If, then, the actual obedience of Christ is thus imputed to all those of whom He is the head, and is counted to them for their justification as their own obedience; in the same way, the actual sin of Adam, who is the type of Christ, is imputed to all those of whom he is the head, and is counted for their condemnation, as their own sin. In writing to those at Corinth, who were ‘sanctified in Christ Jesus,’ the Apostle says, ‘The first man is of the earth, earthy; the second man is the Lord from heaven. As is the earthy, such are they also that are earthy; and as is the heavenly, such are they also that are heavenly. And as we have borne the image of the earthy, we shall also bear the image of the heavenly.’
