How do we know salvation comes through Jesus Christ?

The assurance of salvation through Jesus Christ is firmly established in the New Testament. Romans 7:24-25 illustrates the apostle Paul's own struggle with sin and his ultimate reliance on Christ for deliverance, declaring, 'I thank God through Jesus Christ our Lord.' Additionally, Ephesians 2:8-9 emphasizes that we are saved by grace through faith, a gift from God, which excludes the possibility of boasting in our own works. The centrality of Christ in salvation is further reinforced in 2 Corinthians 5:21, where it states that Christ was made to be sin for us so that we might be made the righteousness of God in Him. This underscores the necessity of looking to Jesus as the sole means of reconciliation to God.
