The Private Moments of Preparation
Where did David get his courage to face Goliath? It didn't just come 'automatically' and it didn't come by looking at himself or psyching himself up. David's courage came from many things, two of which were 1) His private intimacy and communion with God. He knew God in private and He cared about His honor and 2) His private faithfulness in facing the bears and lions to fulfill the seemingly insignificant task God gave him to protect the sheep actually prepared him to publically face the greater bear in Goliath to protect the people of Israel.
