Why is salvation through Jesus Christ alone important?

The importance of salvation through Jesus Christ alone is fundamentally rooted in the doctrine of grace. Romans 9:15-16 emphasizes that salvation is not based on human will or efforts but solely on God's mercy. Jesus’ sacrificial work, as articulated in John 17:4, secured the redemption of His people. Without His atoning sacrifice and perfect righteousness, no one could stand justified before a holy God. Galatians 2:21 further elaborates that if righteousness were attainable by human effort, then Christ's sacrifice would be rendered meaningless. Thus, acknowledging Christ as the sole means of salvation affirms the grace of God and the glory of Christ in the redemption of sinners.
