James 2:14–17
"What use is it, my brothers and sisters, if someone says he has faith, but he has no works? Can that faith save him? If a brother or sister is without clothing and in need of daily food, and one of you says to them, “Go in peace, be warmed and be filled,” yet you do not give them what is necessary for their body, what use is that? In the same way, faith also, if it has no works, is dead, being by itself."
James points out that faith—trusting in Jesus, who saved us and resurrected from the dead—must be accompanied by good works, such as acts of generosity. He argues that saving faith is more than head knowledge. Works are essential; without them, faith is dead.
James 2:26
"For just as the body without the spirit is dead, so also faith without works is dead."
