How do we know salvation is through faith in Christ?

The assurance of salvation through faith in Christ is attested throughout Scripture. The Apostle Paul underscores that it is Christ's work, not our efforts, that secures salvation. Ephesians 2:8-9 clearly states that we are saved by grace through faith, not of ourselves. This theme resonates deeply through the Old Testament, culminating in the New Testament's revelation of Christ as the fulfillment of God's redemptive plan. Thus, true saving faith is not merely about intellectual assent but a deep, abiding trust in the all-sufficient sacrifice of Christ, who has declared, 'It is finished.'
