雅各書2:19 你信 神只有一位，你信的不錯；鬼魔也信，卻是戰驚。
James 2:19 You believe that God is one; you do well. Even the demons believe—and shudder!
Notice here that faith is exercised in two ways.
First, a faith about God meaning that I believe that what is said about God is true, just as I might say I believe that what people say about the Turks, the devil, and hell is true. This kind of believing is more an item of knowledge or an observation than a creed.
The second kind of faith means believing in God—not just that I believe that what is said about God is true, but that I put my trust in him, that I make the venture and take the risk to deal with him, believing beyond doubt that what he will be toward me or do with me will be just as they [the Scriptures] say.…… God makes a person a Christian and obtains all he desires from God. No corrupt or hypocritical heart can have such a faith; this is a living faith as the First Commandment demands: I am your God; you shall have no other gods.（AE 43:24）
