Did you know that David was about half Goliath's height? Goliath was thought to be about 9'7". The average height at the time was about 5' and David was considered to be shorter than average. Yikes!
Goliath and the Philistines were walking around shouting insults and other things that were quite unkind at the Israelite army for 40 days! Talk about bullying!
David wasn't even a soldier. He was only there because he had left his flock of sheep to take some goodies from the kitchen to his brothers. He showed up and upon seeing and hearing what was going on, he started asking questions. What in the world is this? Who is this guy? Why are you putting up with him? And What is going to be done about it?
Finally David told King Saul that he would get rid of this guy and his foul mouth. How absurd this must have looked to Saul and the other soldiers. David was young, he was small, and he was not trained as a soldier.
But David did have experience in fighting lions and bears who wanted to attack his sheep. And he had faith. He had a lot of faith. In his time alone in the field with his beloved sheep, he found time to know his God deeper.
So when the moment came for David to put an end to the stand off between the Israelites and the Philistines, scripture tells us the David ran quickly toward the battle line.
What unusual task is God calling you to? Is someone throwing verbal doubts your way? Do you feel you are not properly prepared? Take another look. Perhaps God has used unusual avenues to prepare you for just this task. I challenge you to run to the battle line. You will not be going alone. The Lord will be with you.
