The sermon centers on the theological mystery of why not all Jews believe in Jesus as the Christ, answering that God's word has not failed, but that salvation is rooted in divine election and faith, not human merit. Drawing from Romans 9–11, it emphasizes that God's choice is sovereign, revealed through history—from Abraham's descendants to Jacob over Esau—and fulfilled in Christ, who is the end of the law and the source of imputed righteousness. The ability to believe, which is a gift from God, is not self-generated nor does it arise from hearing the gospel. Though many Jews heard the message, not all believed, because it was not mixed with God given faith- this unbelief fulfills Scripture, as God anticipated resistance and even used Gentile faith to provoke Israel's jealousy. Ultimately, God has not cast away His people, for a remnant of the Jews is preserved by grace, and all who call on the Lord—Jew and Gentile alike—shall be saved, not by works, but by the grace of God who foreknew, predestined, and calls His people to Himself.
