The Bible has a lot to say about faith there are multiple types of faith mentioned in the Scriptures such as active, common, genuine, great, growing, little, strong, weak, unwavering, and wavering.

Our faith is based on / rooted in God's promises, rather than feelings, or things visible. Great faith holds fast regardless of outward appearances. "And being fully persuaded that, what he had promised, he was also able to perform," (Rom 4:18-22).

Psalms 37:40 Because of their faith in him, their daily portion will be a Father’s help and deliverance from evil. This is true for all who turn to hide themselves in him!
