I found this entry yesterday on Facebook from someone called Drew Yamamoto:
Luther, Calvin, and Barth have all died and gone to heaven. In successive order, each is given an audience with the Lord.
Luther walks in and spends several hours with the Lord. He eventually makes his way out and remarks to the others, “Boy, I understand justification so much better now.”
Calvin then enters the Lord’s house and remains there for several hours. Eventually, he exits and remarks to the others, “Boy, I understand election so much better now.”
Barth then enters and is inside for a very long time. He’s in there for a REALLY long time. Eventually, God walks out and remarks to the others, “Wow, I have no idea what that guy is talking about!”
