David was born the last in his family. He was delegated to all the menial jobs by his family because he was a black sheep, he always tried to rock the boat, he was a rebel and a troublemaker from childhood. He never got along with the establishment, and they tried hard to indoctrinate him into their frame of thinking. His parents could not control him, they sought professional help without desired results.
The problem was David thought he was different from the others as he seemed to remember a lifetime before and connections to who he may actually be.
David pursued his private thoughts and became more separated from the established position of falling in line and thinking like the others, so he was always an outsider to his family, he was always not like the others in his family?
He was in charge of the sheep of his families herds. This was a good place to keep him out of the main stream and away from the public, so he would not embarrass the family.
God decided He needed a king to replace King Saul who became a compromised King because of his pride of being chosen King by God and he became perverted by power.
God anointed David as the next King, because David was Humble. David was tending the sheep when the war broke out against the Israelis from the palestinians.
Davids older brothers all went to fight. King Saul was in charge and at the front giving orders to his men. The Palestinians sent out their great warrior named Goliath. Goliath was 9 feet tall, and musclebound, and all the Israelis were afraid of this "bad ass" because he looked so BIG and so BAD.
David went to the battle formation and King Saul asked for a volunteer to fight Goliath, but no one responded. David spoke up and said, I will go against him. God agreed and caused King Saul to also agree. David was sent out and he took nothing but his shepherds bag with him.
This bag contained his sling shot and nothing else. On his way to confront Goliath David crossed a stream, in this stream David picked up 5 stones, and he put the stones in his shepherds bag.
He kept one stone out and loaded his slingshot, and slung it and hit Goliath right in the forehead and killed him. Then the sheepherder took Goliaths sword and cut his head off.
David killed Goliath with one shot, why did he pick up the five stones to start with if he only needed one?
