Paul reveals God's complete salvation plan in Romans 11:25-36, explaining how both Gentiles and Israel fit into God's redemptive purposes. He describes the fullness of the Gentiles - God's predetermined number of non-Jewish believers who will come to faith. Paul then declares that all Israel will be saved when Christ physically returns to earth and they recognize Him as their Messiah. This understanding of God's irrevocable promises and perfect plan leads Paul to explosive worship, recognizing that everything exists from God, through God, and for God's glory.
