How has God chosen to show mercy to Israel? Some argue that God is done with the nation of Israel and that when Paul says that Israel will be saved, he is speaking of the gathering together of the elect. In this sermon on Romans 11:28–32 titled “Future of the Jews,” Dr. Martyn Lloyd-Jones has a different interpretation of this passage. He argues that the apostle Paul is prophesying of the day when God stirs up the hearts of the people of Israel and causes a great revival amongst them. God will fulfill His promises to the patriarchs and save many of their physical descendants. The hardening that has come upon Israel is only temporary and is used by God to send the gospel to the nations of the Gentiles. Did Israel stumble in order that they might fall? Paul says no. Dr. Martyn Lloyd-Jones says that the church should look forward to the day when God moves and brings a great revival in Israel and brings many to faith in Jesus Christ. This should encourage the church to evangelize the people of Israel, knowing that God has promised to do a great work of salvation among them, bringing many to faith and new life in Christ.
