Okay, it's a little long...but I think it's important for understanding the "Gospel" (the good news Story of Jesus). I think I've gone through this shift a little bit myself in recent years but have found it hard to articulate.
Brad presents the gospel twice, using a couple of chairs to illustrate the relationship between God and people.
The first time is how he used to present it, preach it, and I suspect how many of us first understood it and still understand it: in a legal sense where God is the Judge, and Jesus substitutes himself for our sin on the cross.
The second time there is a shift from God as Judge to God as Healer/Rescuer/Lover. Which Gospel do you identify with? What are the implications?
