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

The apostle Paul's mission was to proclaim the gospel for the obedience of faith among all nations, as stated in Romans 1:5. This underscores the inclusive nature of God's grace, where salvation is not restricted to the Jews alone but is offered to Gentiles as well. The historic promise, beginning with Israel, finds its fulfillment in the spread of the gospel, demonstrating God's desire to be glorified among all peoples. Thus, people from every nation can share in the blessings of salvation through faith in Jesus Christ.
