Without faith, it is impossible to please God, for he who comes to God must believe that he exists and that he is a rewarder to those who earnestly seek him. Hebrews 11:6

You have been saved through faith, it is not of yourselves, it is a gift of God, not of works lest any man should boast. Ephesians 2:8

Now faith is the substance of things hoped for, the evidence of things not seen. Hebrews 11:1

We walk by faith, not by sight. 2 Corinthians 5:7

You have seen and you have believed. Blessed are those who have not seen and yet believed. John 20:29

For we fix our eyes on the things that are not seen, for the things that are seen are temporary but the things that are not seen are eternal. 2 Corinthians 4:18

Abraham believed in God and it was reckoned to him as righteousness. Romans 4:3
