James 1:23-24

For if anyone only listens to the Word without obeying it, he is like a man who looks very carefully at his natural face in the mirror; for once he has looked at himself, he immediately forgets what he looks like.

Our car will start if we turn the key; it is the same as obeying the Word. Faith and the Word need corresponding action for them to work. When we follow the Word, we understand how God works in our lives, and then we SEE God works in our lives. If we entirely disregard God and His statutes, we tie His hands to be able to work on our behalf.
