Faith is "the evidence [conviction, reality, proof] of things not seen" (Hebrews 11:1, 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). Our thinking is limited by our mental ability to understand, assess and determine. Many factors play on the outcome of our thoughts.

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.
