We trust Him with our souls. First, our faith is directed towards the Bible as the Word of God. We believe that the Bible is the Word of God. For example, there are commandments, threatenings, doctrines and promises. Now faith responds to these in quite different ways.
Faith responds to commandments with obedience.
Faith trembles before the threatenings. Confronted by a solemn and sombre divine warning faith is not ecstatic, but tremulous and afraid, responding to the Bible in accordance with the quality of the material presented to it. It also turns these promises into prayers. It has been said that every promise in the Bible is an invitation to prayer. In fact, every promise is a command to pray, because if God promises us something He is directing us to ask for it.
