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].

Yet still, death reigned from Adam until Moses, even over them who had not sinned after the likeness of the transgression of Adam, - who is a type of the Coming One; -

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.

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.

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.

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].

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].

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].
