The Bible is full of stories and instances where God's incredible power helps the small conquer the massive! In this story, all of God's people, including the king, were utterly stuck. They could not take their eyes off of Goliath and look to God. Even though he was a big dude, he was the ONLY obstacle to their success.
All it took one "God-loving" boy to bring him down. One boy who said to the king of Israel, "What are you doing! If you're too afraid to do it, send me in! God and I will take him out!" - And he and God DID!
God has a plan and a purpose for you!
God has a plan and a purpose for every believer!
Satan is dead-set on putting any Goliath he can in your path to prevent you form doing God's will!
Next time your facing one of your "Goliath's" remember, all you need is to Love God and have the faith of David...and a rock!
Philippians 4:13 New International Version (NIV) 13 I can do all this through him who gives me strength.
