You've been dealing with the wrong folks then because all Christians should believe what James says when we says

James 2:14-20, 26 (NET) What good is it, my brothers and sisters, if someone claims to have faith but does not have works? Can this kind of faith save him? If a brother or sister is poorly clothed and lacks daily food, and one of you says to them, “Go in peace, keep warm and eat well,” but you do not give them what the body needs, what good is it? So also faith, if it does not have works, is dead being by itself. But someone will say, “You have faith and I have works.” Show me your faith without works and I will show you faith by my works. You believe that God is one; well and good. Even the demons believe that – and tremble with fear. But would you like evidence, you empty fellow, that faith without works is useless? For just as the body without the spirit is dead, so also faith without works is dead.
