93:4.8

Do you have faith? Have it to yourself before God. Happy is he who doesn’t judge himself in that which he approves. But he who doubts is condemned if he eats, because it isn’t of faith; and whatever is not of faith is sin.

You believe that God is one. You do well. The demons also believe—and shudder. But do you want to know, vain man, that faith apart from works is dead? Wasn’t Abraham our father justified by works, in that he offered up Isaac his son on the altar? You see that faith worked with his works, and by works faith was perfected. So the Scripture was fulfilled which says, “Abraham believed God, and it was accounted to him as righteousness,” and he was called the friend of God. You see then that by works a man is justified, and not only by faith. In the same way, wasn’t Rahab the prostitute also justified by works when she received the messengers and sent them out another way? For as the body apart from the spirit is dead, even so faith apart from works is dead.

For Moses writes about the righteousness of the law, “The one who does them will live by them.” But the righteousness which is of faith says this, “Don’t say in your heart, ‘Who will ascend into heaven?’ (that is, to bring Christ down); or, ‘Who will descend into the abyss?’ (that is, to bring Christ up from the dead.)” But what does it say? “The word is near you, in your mouth and in your heart;” that is, the word of faith which we preach: that if you will confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes resulting in righteousness; and with the mouth confession is made resulting in salvation. For the Scripture says, “Whoever believes in him will not be disappointed.”
