What can the 80's movie Back to the Future teach us about Jesus? A lot actually (and not just how to drive a DeLorean)! While Marty McFly travels to the past to change things, Jesus doesn't want to change our past, instead he wants to redeem it. To redeem our past Jesus frees us from it, he's drawn to it, and he uses it. Our past isn't something to be ashamed of, to Jesus it's something to remember and be thankful for.
