21 For since death happened to a man [i.e., Adam], the resurrection from the dead also happened to a man [i.e., Christ].
1 Corinthians 15:21 Cross References - AUV
John 11:25
25 Jesus said to her, “I am the resurrection and the life; the person who believes in me will live on, even though he dies [physically].
Romans 5:12-17
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].
13 For even before the law of Moses, sin was [being committed] in the world. But man is not responsible for [his] sin when there is no law.
14 Yet [physical] death ruled [over mankind] from the time of Adam to Moses, even over those people who had not sinned the way Adam did. [Now] Adam prefigured the coming of Jesus.
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.
16 And the gift [of salvation] is not like [the effect of] one man’s sin [i.e., Adam’s], for [God’s] judgment of condemnation came [upon mankind] through one man [i.e., Adam], but the free gift [of salvation] came as the result of [the] many sins [of mankind] and [it] made people right with God.
17 For if [physical] death ruled [over mankind] because of the sin of the one man [i.e., Adam], how much more will those who receive the abundance of God’s unearned favor, and the gift of being right with Him, rule in [never ending] life through the one man, Jesus Christ.
Romans 6:23
23 For the wages for sinning is [spiritual] death, but God’s free gift is never ending life in [fellowship with] Christ Jesus our Lord.
1 Corinthians 15:22
22 For as all people die [physically] in [their relationship to] Adam, so also will all people be made alive [physically] in [their relationship to] Christ. [Note: However, some view “made alive” as referring to the new spiritual life given to believers].
