How do we know that salvation is only through Jesus?

The truth of salvation being exclusively through Jesus is firmly established in Scripture, particularly highlighted in John 14:6 where Jesus states, 'I am the way, the truth, and the life; no one comes to the Father except through Me.' This profound declaration emphasizes that only faith in Christ can reconcile us to God. The atoning sacrifice of Jesus on the cross ensures that believers are justified and received into God's presence. Additionally, passages like Acts 4:12 confirm that there is no other name given under heaven by which we must be saved, solidifying the doctrine that Jesus is the only true source of salvation.
