1 Corinthians 15:49

And as we have borne the image of the earthy, we shall also bear the image of the heavenly. [Here the two heads of humanity are contrasted. Adam was a quickening soul, and Christ a quickening spirit (comp. Genesis 2:7; and John 20:22. See also 2 Corinthians 3:17; Romans 8:2; Romans 8:11; John 7:38-39). But of these two heads the natural came first. We are Adam's by generation, and Christ's by regeneration. The life principle of Adam is soul, and he was formed of the earth: the life principle of Christ is spiritual. He was in heaven (John 1:1) and from thence entered the world and became flesh (John 1:14; John 3:13; John 3:21; Philippians 2:6-8; John 1:1-3; Luke 1:35). Now, as the two heads differ, so do the two families, and each resembles its head; the earthly progeny of Adam having earthly natures, and the spiritual progeny of Christ having spiritual and heavenly natures. But in both families the earthly nature comes first, and the spiritual children wait for their manifestation, which is the very thing about which the apostle has been talking, for it comes when they are raised from the dead (Romans 8:29; 1 John 3:2; Romans 8:22-23; 2 Corinthians 5:1-10). Life is not retrogression, but ascension. Therefore he assures them that as they have borne the image of the earthly Adam, so also are they to bear the image of the heavenly Christ, both of whom have the bodies of men, yet bodies differing vastly in glory, power, etc., for one belongs to the earth, dies and returns to it, while the other belongs to the deathless heaven and forever abides there.]
