ONCE UPON A TIME, DAVID FACED A MOUNTAIN NAMED GOLIATH.
When young David came into the scene of the battle, all the soldiers were complainers. Every single one of them! Everyone was saying, "My gosh, look at the giant! Look at those giant legs. 
Look at those giant arms. He's so big. He's a monster. He probably eats his own children for breakfast! And when he's still hungry, he eats his nephews and nieces!”
But David wasn't a complainer. He was a conqueror. He didn't dwell on the mountain. He dwelt on the Mountain Mover, his Father in heaven. He said, "Who is this uncircumcised Philistine that he should defy the armies of the Living God? You come to me with sword and spear and javelin, but I come to you in the name of the Lord Almighty.” 
Don't focus on the mountain. 
Focus on the mountain mover.
