God did the same with David. Everyone overlooked him. When Samuel came to the house of Jesse to anoint a king, David was not even present; no one thought he could be king, not his father, not his brothers, and no, not even the most discerning prophet in the land, Samuel. When David came to the court of Saul, further humbling took place to the point he became a fugitive. There in the caves, abandoned and rejected, he learned to depend on God. Eventually, he became the king of Israel.
Examples can be multiplied, even in minor leaders like Gideon; God chose him because he was from the feeblest clan and the weakest family (Judges 6:15), and when God finally called him to deliver his people, he reduced his army from 32,000 men to 300: humility, dependence, exaltation, repeat.
