Believing God doesn't mean sitting down and enjoying a comfortable feeling while we think beautiful thoughts. Believing God means standing up and facing an impossible challenge without fear of what might happen when we obey God's will.

It's Joshua and the people of Israel crossing the Jordan River and conquering Canaan; it's young David defeating a giant, single handedly. It's Ester in the palace saying "if I perish, I perish" and it's young Mary of Nazareth saying "I am the Lord's servant. May it be me as you have said."  -Warren Wiersbe, Life Sentences
