Bible Verses About Faith

Faith in the Bible is neither blind nor merely intellectual. It is confident trust in God and in what he has revealed, a trust that reaches beyond what the eyes can verify. Hebrews calls it the “assurance of things hoped for,” and the Scriptures show it at work: Abraham setting out without knowing where he was going, the sick reaching for the hem of Christ’s garment, the apostles asking simply, “Increase our faith.” The verses below gather the Bible’s teaching on what faith is, where it comes from, and what it does. They also hold together truths we are tempted to separate: that faith is God’s gift and not our achievement, and yet that it is meant to become active in love and works. For anyone whose faith feels small tonight, remember that Jesus said faith the size of a mustard seed is enough. Each verse here is quoted in the World English Bible, Catholic Edition.

What does the Bible say faith is?

The Bible defines faith in Hebrews 11:1 as “assurance of things hoped for, proof of things not seen.” It is confident trust in God and in what he has revealed, reaching beyond what sight can confirm; as Paul says, “we walk by faith, not by sight” (2 Corinthians 5:7). Scripture is clear that faith is directed at a person, “Have faith in God” (Mark 11:22), and that it is God’s gift rather than a human achievement, “by grace you have been saved through faith . . . it is the gift of God” (Ephesians 2:8). Faith is the doorway to God, for “without faith it is impossible to be well pleasing to him.”

Where does faith come from, and can it grow?

Scripture says faith comes from God through his word: “faith comes by hearing, and hearing by the word of God” (Romans 10:17). It is a gift (Ephesians 2:8), yet it is also meant to grow. The apostles themselves prayed, “Increase our faith” (Luke 17:5), and Abraham “grew strong through faith” by holding to God’s promise (Romans 4:20). Faith deepens through Scripture, prayer, the sacraments, and being exercised, especially in trials. In Catholic teaching, faith is the first of the three theological virtues, infused at baptism and strengthened over a lifetime as we respond to grace.

What does the Bible say about faith and works?

The Bible holds faith and works together. Ephesians 2:8 is emphatic that we are saved “through faith . . . not of yourselves,” so nothing is earned by our efforts. Yet James 2:17 is equally clear: “faith, if it has no works, is dead in itself.” The Catholic understanding is that genuine faith is a living gift that necessarily bears fruit in love; works do not buy salvation, but they are the natural expression of a faith that is truly alive. As Galatians puts it, faith works itself out through love.

How to Pray with These Verses

Faith is God’s gift, so the most honest prayer is often the apostles’ own: “Increase our faith” (Luke 17:5). Begin there, asking God to give what you cannot manufacture. Because faith comes “by hearing . . . the word of God,” feed it with Scripture, reading a passage slowly and letting it shape your trust. When faith feels weak, take Jesus at his word that even mustard-seed faith is enough, and fix your eyes on him, “the author and perfecter of faith” (Hebrews 12:2), rather than on the size of your own believing. And let faith move into action; a single concrete act of love, done in trust, strengthens faith more than an hour of anxious self-examination.
