Romans 5:19
For just as many people [i.e., all mankind] were considered [by God] to be sinners [and thus to suffer physical death] through the disobedience of the one man [i.e., Adam]; even so, many people [i.e., all believing mankind] will be considered right with God [and thus live again] through the obedience of the one man [i.e., Christ].
Philippians 2:8
He humbled Himself [by] becoming obedient [to God] to the point of death, even death on a cross.
Romans 5:12
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].
Romans 5:15
But the free gift [of salvation through Christ] is not [exactly] like the sin [of Adam]. For if many people died [physically] because of the sin of the one man [i.e., Adam], how much more did God's favor abound by [providing] His gracious gift [of salvation] to many people because of the one man, Jesus Christ.
Romans 5:18
So then, just as [God's] judgment came, condemning all people [to physical death] because of one sin [i.e., Adam's]; even so the free gift of being made right with God and [resulting in] life may be received by all people because of one man's [i.e., Christ's] act of righteousness. [Note: This "life" may refer to spiritual life now, or to being made alive in the resurrection, which would reverse the curse of physical death caused by Adam's sin].
2 Corinthians 5:21
God considered Christ to be sinful on our behalf, even though He never sinned, so that we could be considered right with God through Him.
Ephesians 1:6
so that we would praise His glorious, unearned favor, which was freely given to us through the One whom God loved [i.e., Christ].
Revelation 7:9-17
After seeing [all] these things, I looked and there [I saw] a huge crowd, which no one could count, from every nation, and tribe, and race, and language group standing in front of the throne [of God] and in front of the Lamb. They were dressed in white robes and had palm tree branches in their hands.
