Hebrews 11:1-6

Now faith is the certainty of things hoped for, a proof of things not seen. For by it the people of old gained approval. By faith we understand that the world has been created by the word of God so that what is seen has not been made out of things that are visible. By faith Abel offered to God a better sacrifice than Cain, through which he was attested to be righteous, God testifying about his gifts, and through faith, though he is dead, he still speaks. By faith Enoch was taken up so that he would not see death; AND HE WAS NOT FOUND BECAUSE GOD TOOK HIM UP; for before he was taken up, he was attested to have been pleasing to God. And without faith it is impossible to please Him, for the one who comes to God must believe that He exists, and that He proves to be One who rewards those who seek Him.
