I've been reading Moses' story today, and I think I must have experienced something similar to his life. Raised in a family of great faith (his biological family) believing he was positioned to work for God (Acts 7:25) he took action, only to find that he needed a (long) period of humility and service to be prepared for that calling. Yet when God deems him ready for that work Moses would rather argue with his miraculous burning bush than go! Maybe Moses also got too comfortable and self satisfied in his period of training.

"The LORD spoke to Manasseh and his people, but they paid no attention. So the LORD brought against them the army commanders of the king of Assyria, who took Manasseh prisoner, put a hook in his nose, bound him with bronze shackles and took him to Babylon. In his distress he sought the favor of the LORD his God and humbled himself greatly before the God of his fathers. And when he prayed to him, the LORD was moved by his entreaty and listened to his plea; so he brought him back to Jerusalem and to his kingdom. Then Manasseh knew that the LORD is God"
