Faith is “the evidence [conviction, reality, proof] of things not seen” (Hebrews 11:1 Hebrews 11:1Now faith is the substance of things hoped for, the evidence of things not seen.
American King James Version×, emphasis added). Reason is usually based on an analysis of what we see. Our analysis is always tempered by what we know and how our mind works. Jesus’ disciples reasoned as humans do and often missed the point of faith (see, for example, Matthew 16:7-11 Matthew 16:7-11 7 And they reasoned among themselves, saying, It is because we have taken no bread. 8 Which when Jesus perceived, he said to them, O you of little faith, why reason you among yourselves, because you have brought no bread? 9 Do you not yet understand, neither remember the five loaves of the five thousand, and how many baskets you took up? 10 Neither the seven loaves of the four thousand, and how many baskets you took up? 11 How is it that you do not understand that I spoke it not to you concerning bread, that you should beware of the leaven of the Pharisees and of the Sadducees?

Faith is directed toward God and can be blurred by human reasoning. When Jesus walked on the stormy sea, reason told the disciples it was not possible—but faith made it happen. The way to see by faith sometimes requires that we close the eye of human reasoning.
