Hebrews 11:1-6

Now faith is the assurance of things hoped for, the conviction of things not seen. For by it the men of old gained approval. By faith we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible. By faith Abel offered to God a better sacrifice than Cain, through which he obtained the testimony that he was 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 he obtained the witness that before his being taken up he was pleasing to God. And without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who seek Him.
