What does the Bible say about faith in Jesus Christ?

Faith in Jesus Christ is foundational to the Christian faith, emphasizing that believers are justified by faith alone. Romans 3:28 highlights this by stating, 'Therefore we conclude that a man is justified by faith without the deeds of the law.' This faith is not a mere intellectual assent but a trusting reliance on Jesus Christ, who is the justifier. It is through this faith that believers access the grace of God, as repeated in Romans 5:2, indicating that faith opens the door to a relationship with God. Furthermore, Hebrews 11:1 describes faith as 'the substance of things hoped for, the evidence of things not seen,' showcasing the certainty that believers have in the promises of God.
