God’s purpose in establishing a new covenant was not to get rid of his chosen people, but to make room for everyone to enter into his kingdom. Paul told the Romans, ” Because the Jews have been put aside, many other people in the world have been saved from the punishment of sin. Think what it will be like when they are also gathered in. It will be like the dead coming back to life!” (Romans 11:15, NLV). Paul explained that the Israelite’s spiritual blindness was the result of an intentional effort on God’s part to integrate the Jewish and Gentile populations. Paul described it as a grafting, the technique whereby tissues of plants are joined so as to continue their growth together. He stated, “But some of the branches (who are the Jews) were broken off. You who are not Jews were put in the place where the branches had been broken off. Now you are sharing the rich root of the olive tree” (Romans 11:17, NLV).
Paul used the illustration of petrified rock to convey the Jews spiritual condition. Even though God claimed responsibility for hardening the Jews’ hearts, Paul made it clear that it was their unbelief that caused God distance himself from the his chosen people. Paul told the Romans, “It is true. They were broken off because they did not put their trust in Christ. And you are there only because of your faith. Do not be proud. Instead, be afraid. God did not keep the first branches (who are the Jews) on the tree. Then watch, or He will not keep you on the tree” (Romans 11:20-21, NLV). Paul went on to say, “God has said that all men have broken His Law. But He will show loving-kindness on all of them” (Romans 11:32, NLV). The end goal of God’s plan of salvation was to show mercy on everyone. That’s why he let the Jews go their own way for a period of time, so that we can benefit from what is now referred to as the age of grace.
Paul concluded his explanation of God’s casting away of the Jews with a doxology, a natural outpouring of his praise to God. Paul rejoiced by stating:
“God’s riches are so great! The things He knows and His wisdom are so deep! No one can understand His thoughts. No one can understand His ways.” The Holy Writings say, “Who knows the mind of the Lord? Who is able to tell Him what to do? Who has given first to God, that God should pay him back?” Everything comes from Him. His power keeps all things together. All things are made for Him. May He be honored forever. Let it be so. (Romans 11:33-36, NLV)
Paul was truly amazed by God’s ability to figure out a way to save both Jews and Gentiles with a single sacrifice, the death of Jesus on the cross. Paul referred to God’s grace as great riches. The combination of God’s wisdom, his practical skill and his knowledge or complete and absolute understanding of how the world works made it possible for him to devise a plan of salvation that was perfect in every way. Therefore, it is inevitable that the Jews will one day return to God’s favor as predicted by many of the Old Testament prophets (Romans 11:24-25).
