Abraham was guilty of duplicity, and yet he became the man of faith and the friend of God. And Moses, another clay pot, had his halting speech and quick temper; yet he was the man chosen to make a nation and to commune with God, to receive the law.
David, another clay pot, was guilty of adultery and murder, but he repented and became a man after God’s own heart and the sweet singer of Israel for all time.
And then there was Isaiah, who in the presence of God admitted that he was a man with a dirty mouth. And yet it was he that God called and used mightily.
