Faith is confident trust in God and His promises, even when we cannot see the outcome. Hebrews 11:1 defines faith as 'the assurance of things hoped for, the conviction of things not seen.' Biblical faith involves belief, trust, and active obedience to God's Word.
Why this answer? It starts with Hebrews 11:1, then cross-checks Romans 10:17 and James 2:17 so the summary stays anchored in Scripture.
This answer explains faith according to the Bible as living trust in God: assurance, belief, obedience, endurance, and confidence in Christ's promises.
Faith in the Bible is far more than intellectual agreement—it is a living trust that shapes how believers relate to God and navigate life. Hebrews 11:1 defines faith as the assurance of things hoped for, the conviction of things not seen, establishing that biblical faith bridges the gap between promise and fulfillment. Throughout faith and scriptures, we see this trust demonstrated: Abraham left his homeland, Moses chose suffering over Egypt's treasures, and David faced Goliath—all by faith in Christ's coming redemption. Jesus taught that even mustard seed faith could move mountains, emphasizing quality over quantity. The relationship between faith without works is clarified by James, who insists that genuine belief produces action—we walk by faith, not by sight. Paul taught that believers are justified by faith and protected by the shield of faith against spiritual attack. This trust in God is both a gift of grace and a daily choice to rely on His character rather than human understanding.
“Now faith is the assurance of things hoped for, the conviction of things not seen.”
- Hebrews 11:1
Faith comes by hearing God's Word (Romans 10:17)—so read Scripture regularly. Pray for faith, as the disciples did: 'Increase our faith!' (Luke 17:5). Remember God's past faithfulness. Take small steps of obedience—faith grows through exercise. Surround yourself with other believers who encourage faith.
Grace is God's unmerited favor—His love and mercy given freely to humanity despite our unworthiness. In Christian theology, grace is the foundation of salvation, given through faith in Jesus Christ, not earned by works (Ephesians 2:8-9).
Justification is God's act of declaring sinners righteous based on Christ's work, not our own merit. When we trust in Jesus, His righteousness is credited to us and our sins to Him. We're declared 'not guilty' before God—a legal standing, not gradual transformation. It's by faith alone in Christ alone.
