There is a story in the Bible about the choosing of David to be the second king over Israel. In the story, the prophet Samuel visits David’s father, and essentially begins a “training academy” from among David’s brothers. Only one of the sons was missing, and that was David. He was young; he was not old enough, not strong enough, not equipped. At least that was the human perspective. But in the economy of God, David was the one rightly equipped (or perhaps at that point being equipped) to become the king.
