Now peace with God doesn't mean that our lives won't have trouble, struggle, pain, or hurt. Not at all - those things are still so present and sometimes it sure seems like they are surrounding us to the point of suffocation. And yet, our status with God means that we can have peace with Him in the midst of that chaos.
The story of the the "sinful woman" in Luke 7:36-50 is a beautiful illustration of this. She was someone who lived in a world of struggle and chaos. Her encounter with Jesus changed that forever - they shared an intimate moment. Scripture doesn't record anything that she said, only her tears. But Jesus told her that her sins were forgiven, her faith had saved her, and that she should go in peace. Did she go out of that house suddenly able to easily forsake her sinful life and into a world of butterflies and rainbows? Not at all - but from then on, she was able to say that she was forgiven, and that she had peace with God.
