This past Sunday, I did my best to answer as plainly and clearly as I could from 1 Corinthians 15:1-5 the question: what is the gospel?
According to Matt Chandler, I only hit the gospel "on the ground" in that sermon. I didn't get into the gospel "in the air". But I'm with him wholeheartedly that both are precious and ought to be unpacked regularly. In fact, if I'd gone on in 1 Corinthians 15 I would have gotten there, but only so much can be said in 45 minutes!
