One of Graham's favorite sayings is, "God isn't an evangelical."
His point is that God isn't worried about our sin because He has already dealt with it. He isn't angry or disillusioned with us ("because He never had any illusions about you to start with.")
Sin is the result of broken identity.
The conviction from the Holy Spirit is not about sin, it is always about restoring identity.
Our growth is connected to our understanding of God, and our responsibility is to deliberately cooperate with His Spirit in His work of restoration in our lives.
The evangelical perspective is on a judgmental God. The message of the gospel is first and foremost a message of repentance, that sinners face an angry God. Even if the focus is on the love of God, there is still an emphasis on getting right with God, and once saved, a focus on getting all of the details of your doctrine correct.
The missional perspective seems to be that God loves us while we are yet sinners and that our sins are already forgiven before we even repent of them.
I think one of the biggest offenses of the evangelical gospel has been confronting people on the basis of their sin rather than introducing them to the love, grace, and mercy of God.
Do we dare run around in the ridiculous lavishness of His grace and trust others with that abundance of grace? What could happen if we let people be free of judgment, willy-nilly, without the restraint of guilt? Could their mistakes be any worse than the mistakes of legalism?
