The Bible teaches that salvation is not earned by human works but is received through faith in Jesus Christ, whose righteousness is imputed to believers. Key verses include Ephesians 2:8-9, which states that salvation is "not of works, lest any man should boast," and Philippians 3:9, which contrasts having one's own righteousness with receiving "that which is through the faith of Christ." Additionally, John 14:6 declares that Jesus is the only way to the Father, and Revelation 21:27 notes that nothing defiling can enter heaven, emphasizing that human efforts are insufficient without Christ's atoning sacrifice.
