Habakkuk 2:4 Behold, his soul which is lifted up is not upright in him: but the just shall live by his faith.

Matthew 9:29 Then touched he their eyes, saying, According to your faith be it unto you.

Hebrews 11:1, 3, 6 Now faith is the substance of things hoped for, the evidence of things not seen. … Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear. … But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
