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].

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].

Was this [commandment] then, which was intended for my good, [actually] responsible for my [spiritual] death? Certainly not! But so that sin could be seen as [truly] sinful, it produced [spiritual] death in me through something that was good [i.e., the commandment against sinning]. This was so that, by means of the commandment [against sinning], sin could be seen as extremely sinful.
