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].

Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come.

But God's free gift is not like Adam's offense. For if many people died as the result of one man's offense, how much more have God's grace and the free gift given through the kindness of one man, Jesus the Messiah, been showered on many people!

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.

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].

And if Christ lives in your hearts, even though the body is [doomed to] death because of [Adam's ?] sin; yet the spirit is [destined to] live [forever] because of being [made] right with God. [Note: Some take "spirit" here to be "Spirit" and make it "The Holy Spirit gives you life." See next verse].

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].

for we are members of his body, as if taken out of his flesh, and of his bones, as Eve was out of Adam's.
