James 2:14-17
What does it profit, my brethren, if someone says he has faith but does not have works? Can faith save him? 15 If a brother or sister is naked and destitute of daily food, 16 and one of you says to them, “Depart in peace, be warmed and filled,” but you do not give them the things which are needed for the body, what does it profit? 17 Thus also faith by itself, if it does not have works, is dead.
Romans 10:9
that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved
