The only way we can ever fight our battles is with the armour of God. In 1 Sammuel chapter 17, a young shepard boy named David is called by God to fight Goliath, a Philistine soldier. Throughout the chapter David illustrates the type of faith and trust that we should have in the Lord. By entrusting in the Lord we are promised that He will strengthen our hearts and provide us courage to fight the "Goliaths" of our lives.
