Ted Tripp is an interesting character, because he really does seem to have a good grasp on grace, IF he could get out of his head that spanking is a biblical command.
He seems to know there's a disconnect too, because on his videos he says repeatedly that he tells his kids he doesn't understand the connection between the heart and the rear end, but God is the one that designed it that way, so who is he to question? Ugh... I really think he would be GBD if he could get that idea out of his head.
