How do we know that God saves Gentiles?

The sermon highlights that the grace of God is extended beyond His chosen people, Israel, to the Gentiles. This is emphasized in various scriptural references, notably Acts 13:48, which states that the Gentiles were glad and glorified the Word of the Lord, and as many as were ordained to eternal life believed. This underscores that God's redemptive purpose was to incorporate Gentiles into His covenant community, demonstrating His sovereign grace that reaches all humanity regardless of ethnic background.
