If leaders want to lead for the long term, they must keep learning continuously. For yesterday's insight can already be worthless today. That is why an ongoing readiness for reflection and learning is essential for a leader. God is the potter and we are the clay. He will do what pleases him, and we must allow him to keep shaping us.
Jeremiah 18:18 Then said they, Come, and let us devise devices against Jeremiah; for the law shall not perish from the priest, nor counsel from the wise, nor the word from the prophet. Come, and let us smite him with the tongue, and let us not give heed to any of his words.
