How do we know that Christ is our only Savior?

The fact that Jesus Christ is the only Savior is foundational to the Christian faith, deeply rooted in both the Old and New Testament teachings. In 2 Corinthians 11, Paul stresses that he preached Christ and Him crucified, underscoring that salvation can only be found through Him. This is echoed throughout the Bible, where passages declare that there is no other name under heaven given among men by which we must be saved (Acts 4:12). The assurance that salvation rests solely in Christ's finished work grants believers security and hope, reaffirming that Christ's righteousness and grace alone are sufficient for redemption.
