1 Corinthians 15:48
Just as earthly people are like the man who came from dust; so heavenly people are like the man who came from heaven.
Philippians 3:20-21
But we are [really] citizens of heaven and we are waiting for a Savior [to return] from there, the Lord Jesus Christ,
John 3:6
Whoever is born from human parents is a human being; and whoever is born from the Holy Spirit is a spiritual being.
Romans 5:12-21
Therefore, just as sin came into the world through [the action of] one man [i.e., Adam] and [physical] death through that sin, so [physical] death has spread to all people, because all people have sinned. [Note: This difficult passage (verses 12-21) seems to be saying that the entire human race must experience physical death because of Adam's sin (I Cor. 5:22), which is somehow considered to be everyone's sin. See Murray, pp. 180-187, for a thorough discussion].
1 Corinthians 15:21-22
For since death happened to a man [i.e., Adam], the resurrection from the dead also happened to a man [i.e., Christ].
