You Gentiles are like branches of a wild olive tree that were made to be part of a cultivated olive tree. You have taken the place of some branches that were cut away from it. And because of this, you enjoy the blessings that come from being part of that cultivated tree. But don't think you are better than the branches that were cut away. Just remember that you are not supporting the roots of that tree. Its roots are supporting you.
Maybe you think those branches were cut away, so that you could be put in their place. That's true enough. But they were cut away because they did not have faith, and you are where you are because you do have faith. So don't be proud, but be afraid. If God cut away those natural branches, couldn't he do the same to you?
Now you see both how kind and how hard God can be. He was hard on those who fell, but he was kind to you. And he will keep on being kind to you, if you keep on trusting in his kindness. Otherwise, you will be cut away too.
If those other branches will start having faith, they will be made a part of that tree again. God has the power to put them back. After all, it wasn't natural for branches to be cut from a wild olive tree and to be made part of a cultivated olive tree. So it is much more likely that God will join the natural branches back to the cultivated olive tree.
The People of Israel Will Be Brought Back
My friends, I don't want you Gentiles to be too proud of yourselves. So I will explain the mystery of what has happened to the people of Israel. Some of them have become stubborn, and they will stay like that until the complete number of you Gentiles has come in. In this way all of Israel will be saved, as the Scriptures say, "From Zion someone will come to rescue us. Then Jacob's descendants will stop being evil. This is what the Lord has promised to do when he forgives their sins."
The people of Israel are treated as God's enemies, so that the good news can come to you Gentiles. But they are still the chosen ones, and God loves them because of their famous ancestors. God doesn't take back the gifts he has given or forget about the people he has chosen.
At one time you Gentiles rejected God. But now Israel has rejected God, and you have been shown mercy. And because of the mercy shown to you, they will also be shown mercy. All people have disobeyed God, and that's why he treats them as prisoners. But he does this, so that he can have mercy on all of them.
Who can measure the wealth and wisdom and knowledge of God? Who can understand his decisions or explain what he does? "Has anyone known the thoughts of the Lord or given him advice? Has anyone loaned something to the Lord that must be repaid?" Everything comes from the Lord. All things were made because of him and will return to him. Praise the Lord forever! Amen.
