Loved this quote I read on Justin Taylor's blog today:
@J.D. Greear: Saying “Preach the gospel; if necessary use words” is like saying “Tell me your phone number; if necessary use digits.”
The gospel is a message. If you take out the words, you have no gospel!
I totally agree, and in case anyone thinks this is saying holiness is not necessary to the Christian life, it's not. It's just affirming that the gospel IS the 'word' and has to be preached. It should go without saying that preaching the gospel has a much greater effect if the one preaching lives a holy and sacrificial life.
