1. God's gifts and call are irrevocable (25-29)

God keeps his promises by any means. He promised to send the Deliverer, and he sent Jesus the Deliverer from Zion to take away the sins of the world. God used even Israel's disobedience. Because of Israel's disobedience, a door of salvation was opened to the Gentiles. But what about the Jews who rejected God's Messiah? Are they without hope? No. God continues to love them and to call them to repent and receive the Savior Jesus. God doesn't give up on anyone--but he doesn't compromise. The only way of salvation is through Jesus.

2. So that he may have mercy on all (30-36)

Some people live with the mistaken idea that they are not sinners. They do not realize that they are captives of the sinful nature. So they do not repent and thus cannot taste the mercy of God. God consigned all men to disobedience so that all might repent and be forgiven through the blood of Jesus. All people need God's mercy; I need God's mercy.

Application: Lord, indeed your thoughts are inscrutable and your ways are past finding out. I praise you for the depth and riches of your wisdom and mercy.
One Word: God's call is irrevocable
