How do we know redemption by the Son of God is true?

Redemption by the Son of God is foundational to the Christian faith. In Titus 3:5-6, we see that salvation comes not by our works but through God's mercy and the washing of regeneration. Hebrews 9:12 also emphasizes that Christ, through His own blood, has obtained eternal redemption for us. The certainty of this redemption is rooted in God's faithfulness and the perfect, sinless life of Jesus, which provides a complete and everlasting salvation. This truth is further supported by Acts 4:12, which teaches that there is no other name under heaven given among men whereby we must be saved, underscoring the uniqueness and sufficiency of Christ's redemptive work.
