After escaping from the Motilone, what inspires Bruce to keep walking after he has been traveling for five days?

By the fifth day after Bruce escaped from the Motilone, he is ready to give up walking and die. But he finds bananas floating in the river near where he was walks. Then he remembers a verse in the Bible about how God prepares a table in the midst of enemies. That makes him think about the bananas. He decides that God has shown him the bananas when he needs them. He believes surely God can lead him to people. So Bruce begins walking again.
