"Just as a man cannot live in the flesh unless he is born in the flesh, even so a man cannot have the spiritual life of grace unless he is born again spiritually. This regeneration is effected by Baptism: "Unless a man is born again of water and the Holy Spirit, he cannot enter into the kingdom of God" (Jn 3:5)"

The earthly form of Christ is the form that died on the cross. The image of God is the image of Christ crucified. It is to this image that the life of the disciples must be conformed; in other words, they must be conformed to his death (Phil 3.10, Rom 6.4) The Christian life is a life of crucifixion (Gal 2.19) In baptism the form of Christ's death is impressed upon his own. They are dead to the flesh and to sin, they are dead to the world, and the world is dead to them (Gal 6.14). Anybody living in the strength of Christ's baptism lives in the strength of Christ's death.
