What does the Bible say about God's mercy towards Gentiles?

In Romans 9:24-26, the Apostle Paul emphasizes that God's mercy extends beyond the Jewish people to include Gentiles. He cites the prophecy from Hosea, which states that those who were not previously regarded as God's people would be called the children of the living God. This inclusion of Gentiles into God's redemptive plan illustrates God's sovereign grace and His intention to save a multitude from all nations, demonstrating that His mercy is not confined by nationality or ethnicity but is bestowed according to His will and purpose.
