How do we know God's grace is for all people?

The scope of God's grace extends beyond the Jewish people to all nations, as indicated in Psalm 96, which calls for the nations to rejoice in the glory of the Lord. The New Testament illustrates this further; for example, Romans 9-11 explains God's plan of election includes Gentiles, showcasing His sovereignty in selecting a people for Himself from every tribe and nation. Understanding that grace is not limited to ethnicity but is offered freely to all who believe strengthens our comprehension of God’s expansive love and mercy.
