Psalm 78:70 He also chose David His servant, And took him from the sheepfolds;
When others were looking to the sons of Jesse as soldiers, leaders and worthy sons, David was being quietly ignored as the lowly shepherd boy.
Samuel was told to reject each of the older brothers and to even ask for more children when David had been left out of the selection to start with.
Moses was tending to sheep at the time he was called to serve God.
If we are willing servants to start with God will be able to use us without having to fight us for obedience!
