The account of David and Goliath is always portrayed as a huge win for the underdog. But David actually had a tremendous, unbeatable advantage. He had an unshakable conviction in the power and help of the Lord, as he stood to defend Him. This conviction sharply contrasted not only with Goliath, but with the Israelite people. David's example helps identify 4 convictions that define God's people--those who love and fully trust the Lord.
