The Bible tells us in Hebrew 11:1-6, "Faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good testimony. By faith we understand that the words were framed by the word of God, so that the things which are seen were not made of things which are visible. By faith Abel offered to God a more excellent sacrifice than Cain, through which he obtained witness that he was righteous, God testifying of his gifts; and through it he being dead still speaks. By faith Enoch was taken away so that he did not see death, and was not found, because God had taken him; for before he was taken he had this testimony, that he pleased God. But 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 diligently seek Him."
