" Much of our problem is not, as is often said, that we have failed to get what is in our head down in our heart. Much of what hinders us is that we have had a lot of mistaken theology in our head and it has gotten down into our heart. And it is controlling our inner dynamics so that the head and heart cannot, even with the aid of the Word and the Spirit, pull one another straight. "
