Bible verses about faith

Faith, in the Bible, is neither absolute certainty nor optimism. Hebrews defines it as "assurance of things hoped for, proof of things not seen" — a trust that rests on the One who promised, not on the visibility of the result. It shows up in ordinary people: a father who says "I believe, help my unbelief", a woman who touches the hem of a cloak, a centurion who trusts a word spoken from a distance. Jesus says faith the size of a mustard seed already moves mountains, which suggests the point is not the size of the faith but who it leans on. The verses below are for those starting out, for those whose faith feels small and for anyone who wants to understand where it comes from: "faith comes by hearing".
