Hebrews 11:1, 5-6

Now faith is the assurance of things hoped for, the conviction of things not seen.

By faith Enoch was taken up so that he should not see death, and he was not found, because God had taken him. Now before he was taken he was commended as having pleased God. And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.
