How do we know Christ is the Savior of His people?

The claim that Christ is the Savior of His people is supported throughout the New Testament, where it is noted that He came to save sinners (1 Timothy 1:15). The central theme of Scripture is the revelation of Christ, who fulfills the law and the prophets as the promised Messiah. In Acts 28:28, Paul proclaims that the salvation of God has come to the Gentiles, affirming that God's redemptive work is not confined to the Jews but is extended to all whom He has chosen. The essence of Christ’s mission is captured in His own words in John 3:16, underscoring that God sent His Son so that whoever believes in Him shall not perish but have eternal life. This testimony shows that every drop of His blood was efficacious for the redemption of His people, leaving no one behind, as none for whom He died will be lost.
