Born into a new family, a son of God, by God's adoption. Born from above. Re-make us to pure person. Adam was perfect until he sinned. Changed from normal humanity to spiritual child of God.
New birth equals new creature.
Desire for God things. The purpose for man to become born-again is a child and his Father God having fellowship. God created man for that reason. Man can then enjoy God's love, mercy, and grace in an everlasting relationship with his heavenly Father. Man can think and reason.
