Hebrews 11:1, 5-6

Now faith is the substance of things hoped for, the evidence of things not seen.

By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God. 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.
