Expositor's Bible Commentary Commentary Hebrews 11:6

"And without faith it is impossible to be well-pleasing [unto him]; for he that cometh to God must believe that he is, and [that] he is a rewarder of them that seek after him." — Hebrews 11:6 (ASV)

Though the OT does not say that Enoch had faith, the author goes on to explain why he can speak of it so confidently. It is impossible to please God without faith, and Enoch pleased God. Therefore, it is clear that he must have had faith. The author lays it down with the greatest of emphasis that faith is absolutely necessary. He does not say simply that without faith it is difficult to please God; he says that without faith it is impossible (GK 105) to please him! There is no substitute for faith. He goes on to lay down two things required in the worshiper. First, he must believe that God exists. This is basic. Without it there is no possibility of faith at all. But it is not enough of itself. After all, the demons can know that sort of faith (James 2:19). There must also be a conviction about God’s moral character, belief “that he rewards those who earnestly seek him.” Without that deep conviction, faith in the biblical sense is not a possibility.
