Parker has a better option. Pull apart that circle you are holding and give one end of the strip a half-twist. Now rejoin the ends. What you have in your hands is a Möbius strip, named after the German mathematician who described it. If you trace with one finger around the strip, you’ll discover that the inside becomes the outside and the outside the inside. Now we are holding a powerful metaphor, a picture of life in the Spirit. This is a good model for what happens to us when we encounter the true God.
