Hebrews 11;6 But without faith it is impossible to please him; for he that cometh to God must believe he is, and that he is a rewarder of them that diligently seek him.
James 2;14-26 What doth it profit, my brethren, though a man say he hath faith, and have not works? If a brother or sister be naked and be destitute of daily food, And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit? Even so faith, if it hath not works is dead, being alone. Yea a man say, Thou has faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works. Thou believest that there is one God; thou doest well: the devils also believe, and tremble. But wilt thou know, O vain man, that faith without works is dead? Was not Abraham our father justified by works, when had offered Isaac his son upon the alter? Seest thou how faith wrought with his works, and by works was faith made perfect? And the scripture was fulfilled which saith, Abraham believed God and it was imputed unto him for righteouness, and he was called a friend of God. ye see then how that by works a man is justified, and not by faith only. Likewise Rahab the harlot justified by works, when she had received messengers, and had sent them out another way? For as the body without spirit is dead, so faith without works is dead also.
Faith without action is self-deception.
