Abraham's faith did not become weak [even though] he was about one hundred years old and considered his body almost dead and Sarah's womb incapable of conceiving a child.

For these are the words of the promise [Gen. 18:10], "I [i.e., God] will come at the appointed time and Sarah will have a son."

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].

Now in response to the [proclamation of the] good news [about Christ], the Jews became [God's] enemies for the sake of you [Gentiles]. But concerning [God's] select people, these Jews became [God's] dearly loved ones for the sake of their forefathers [i.e, who believed God's promises regarding their descendants].

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.

This means that it is not the physical descendants [of Abraham] who are God's children, but it is the children [born] according to [God's] promise who are [Abraham's true] descendants.
