"When I hear a sermon that is essentially law-driven, that is, asking the law to do what only the grace of Jesus Christ can accomplish, I am immediately concerned about the preacher. I immediately wonder about his view of himself, because if he had any self-consciousness about his own weakness and sin, he would find little hope and comfort for himself and his hearers in that kind of sermon.
You see this dynamic in the Pharisees. Because they thought of themselves as righteous, perfect law givers, they had no problem laying unbearable law burdens on others. Their misuse of the law had its roots not only in bad theology but also in ugly human pride. They saw law keeping as possible, because they thought they were keeping it. And they thought that others should get up and keep it as well as they did. They were the religious leaders of their day, but they were arrogant, insensitive, uncompassionate, and judgmental. They were not part of what God was doing at the moment; no, they were in the way of it."
