For even before the twins were born, and therefore had not done anything good or bad, Rebecca was told [Gen. 25:23], "The older one [i.e., Esau] will serve the younger one [i.e., Jacob]." This was so that God's purpose of choosing and calling [whomever He wanted to] might prevail, instead of [it depending on] what a person did.

Just as it is written [Mal. 1:2-3], "I [i.e., God] loved Jacob, but hated Esau."

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].
