Where is the "REPENT!" in today's preaching? It just isn't part of the evangelical fabric that's in fashion these days. Have we become so afraid that people will not respond to that nasty little word that we have abandoned it and now depend on manipulation and marketing instead? When we rely on such measly human efforts that utilize enticement and stroke the flesh, what sacrifice is any respondent prepared to make?
The discipleship crisis the American church is in today starts with the message that initially enlists today's supposed disciples. Folks that enter thinking they don't have to turn, won't turn after they enter. I'm not a fan of fire and brimstone preaching--faith, not fear, is the only motivation that sustains a life of following Jesus--but to become a Christian a person must embrace their own death and trust Christ to raise them to a new (and better) life. People today, though all-modern-and-educated, must still hear and respond to the call to repent and follow Jesus, as any disciple in any former age did.
Christianity is about a radical change in direction, a night and day difference in one's life. The result of a new birth cannot be the same old, same old, for birth means leaving an old way of life for a new one, or it's not birth at all. For those would who style themselves as radical and innovative preachers in this day and age, the message that actually matches that characterization starts with the word REPENT! Now that's a radical invitation that stands a shot at producing new life.
