What does the Bible say about Gentile salvation?

In Acts 11:1-18, the Apostle Peter reports to the Jewish brethren that Gentiles received the word of God and were saved, demonstrating that God's plan for salvation extends beyond the Jews. This was a radical shift in understanding for the early Church, where many still held to the belief that salvation was exclusively for the Jews. Peter's realization, prompted by a divine vision and the Holy Spirit, confirms that all who believe, regardless of their ethnic background, can become partakers of the grace of God, as seen in Colossians 3:11 where there is neither Greek nor Jew in Christ. This foundational truth emphasizes that God's redemptive plan through Christ is for people from every nation and background, highlighting the inclusive nature of the Gospel.
