The core of this message, I submit, is correct. There are times for us to exhort one another to good deeds as well – always rooting such words of law in the mercies of Christ (see the beginning of Romans 12 and here for more about the pastoral considerations related to this) – but the fact is that all of us need to hear the kinds of words that Pastor Tullian Tchividjian shares here. Um, I can identify with the story he shares about his own sinful pride.
Yes, would that all persons in the megachurches of America were hearing sermons like this. I do pray that the Lord would bless him in his endeavors to make this word more well known.
