As Paul builds his case for unconditional election, he proceeds to his second example of Jacob and Esau. These men were twin sons of Isaac and Rebekah and grandsons of Abraham. Yet by God’s choice, before they born, Esau was passed over and became a son of derision while Jacob was made the son of the promise and blessed of God. God did this for the glory of His name, so that His purpose according to His choice would stand.
