What does it mean to have faith according to the Bible?

Faith, in the biblical sense, is not merely intellectual assent but involves a deep-rooted trust in Jesus Christ as Lord and Savior. In John 9, after the blind man receives his sight, he expresses faith in Jesus by openly acknowledging His power and divinity. Jesus emphasizes that the work of God is to believe in Him whom He has sent (John 6:29). This faith is also accompanied by repentance and a recognition of one’s sinfulness. Genuine faith reflects a transformation of the heart, leading to worship, as the healed man displays when he says, 'Lord, I believe', at which point he worships Jesus. This underscores that true faith inevitably responds in adoration and commitment to Christ.
