What does it mean that salvation is through faith in Christ alone?

Salvation through faith in Christ alone signifies that our justification before God is only achieved through faith in the Lord Jesus Christ as our righteousness. Romans 4 articulates that it is not by works but through believing the promises of God that we are saved. This doctrine emphasizes the exclusivity of Christ's atoning work and the sufficiency of His sacrifice for our sins. It assures believers that they can rest entirely in Him, as the only basis for their salvation, giving all glory to God.
