He who makes big promises and speaks empty words appears to have great faith. But actually, he has no faith at all. If you have faith, you should take off your coat and let another put it on. You should invite others to eat your food. If you only talk about faith, you do not have it. Hence, James concluded that this kind of talk is sin. The point here is not that faith is wrong, but that speaking empty words is wrong. Last night we talked about faith. The night before last we also talked about faith. But we have not paid attention to this kind of faith yet. Inasmuch as James was opposed to it, we are opposed to it, too. It is useless to speak empty words.
Verse 19 says, "You believe that God is one. You do well; the demons also believe and shudder." This is a very strong word. You believe that God is one. You do well to believe this. The demons believe this too, but they shudder. Please take note of the word "and." The question today is not whether or not you believe. If you say that you believe, no one can say that you do not. The problem is that even the demons believe. But they do not have peace. The apostles did not write to the demons, saying, "Peace be unto you. May God bless you and the fallen angels with you." Although the demons believe, they shudder. That kind of faith does them no good. Their faith makes them shudder and lose their peace. If you say that you believe, is your believing the kind of believing that the demons have? James's words are very strong and sharp. Undoubtedly, you do believe in God. But the demons believe, too. You say you believe, but at the same time you shudder, fear, and are nervous. Therefore, you are standing on the same ground as the demons. When we read on, we understand what James is against. James is not against faith at all. He is against a certain kind of faith. James is not saying that faith will not justify. He is merely saying that this certain kind of faith will not justify.
In verse 20 James calls these people by their names. He calls them what they are. He does not call them brothers and sisters. He does not call them his beloved, as Paul did; nor does he call them fathers or little children, as John did. Rather, he calls them vain men. "But are you willing to know, O vain man, that faith without its works is useless?" Notice the words "are you willing" here. That James says this proves how hard their attitude is. When others speak God's Word to them and warn them, they still will not believe. Hence, James asks if they are willing to know that this kind of faith is dead. It is not that they are unable to know or that they are unable to be clear. It is not that no one will teach them how to know. It is simply a matter of their not being willing to know. Suppose I try to speak to a brother, and he looks away. When I try again, he looks the other way. When I try a third time, he begins to talk to another brother. I would then say, "Brother, are you willing to listen or not?" This is what James is saying here. Are you willing to know that this kind of faith without works is dead?
When we read the Bible, we have to ask God to show us the circumstances under which the portion was written. James calls this kind of people vain men. They put everything out in the open for others to see and talk about and thus exhibit themselves. They want to have a share in everything. They want to speak up wherever they are. James says that this kind of person must be subdued. O vain man, are you willing to know that this kind of faith is useless? Because they will not listen after he has spoken so much to them, he has to taunt them and shout at them a little.
