We are called by grace, and not by any other means. Look at the people in the Bible that God has called: they messed up, yet they were stilled called of God. Other than Jesus Christ, who is the perfect one, God will not choose perfect vessels. They do not exist. God chose marred vessels. God calls and God chooses, and don’t judge whom God has called, for by grace we are called. God is the replacing dirty garments with clean garments.
