James 2:19-23

2:19 You believe that God is one; well and good. Even the demons believe that – and tremble with fear.

2:20 But would you like evidence, you empty fellow, that faith without works is useless? 2:21 Was not Abraham our father justified by works when he offered Isaac his son on the altar? 2:22 You see that his faith was working together with his works and his faith was perfected by works. 2:23 And the scripture was fulfilled that says, “Now Abraham believed God and it was counted to him for righteousness,” and he was called God’s friend.
