James says that a person can't even be saved through dead faith and then uses Abraham's obedience as an example.
14 What does it profit, my brethren, if someone says he has faith but does not have works? Can faith save him?
24 You see then that a man is justified by works, and not by faith only.
James says that we're JUSTIFIED through our obedience, not through dead faith. If salvation is itself justification or if we're justified - saved "by faith" - then justification requires works. Not works "of the law," not works "of yourselves," but of the works God created us to walk in. His works. The works he commanded.
There’s the very argument you are missing.
Once again, you make my point about cherry picking verses. You go from 14 to 24, and act as if the rest is meaningless.
What use is it, my brethren, 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,” and yet you do not give them what is necessary for their body, what use is that? Even so faith, if it has no works, is dead, being by itself. But someone may well say, “You have faith and I have works; show me your faith without the works, and I will show you my faith by my works.” You believe that God is one. You do well; the demons also believe, and shudder. But are you willing to recognize, you foolish fellow, that faith without works is useless? Was not Abraham our father justified by works when he offered up Isaac his son on the altar? You see that faith was working with his works, and as a result of the works, faith was perfected; and the Scripture was fulfilled which says, “And Abraham believed God, and it was reckoned to him as righteousness,” and he was called the friend of God.
— James 2:14-23
Here’s the argument that James is making, which he will support with the verses that follow:
says he has faith but he has no works? Can
that faith save him?
What faith is he talking about? Said faith. It’s right there. And then he goes on to explain that just saying you have faith doesn’t make it so. If you have faith, works will follow.
