As an athlete, I put on my protective equipment every time I go on the ice. Every piece serves a purpose. I learned the hard way that there are no spare parts. At the end of practice one day, there were just two of us left out on the ice. I removed my mouth guard to speak with the equipment manager—just as my teammate took one last slap shot. Unbelievably, the puck deflected off the cross bar and smacked me in the mouth, knocking out my two front teeth. I was not pleased. My teeth had survived almost twenty years of hockey, since I first laced on skates as a small boy. Now I had to endure countless dentist appointments, root canals, even false teeth—all because I let down my guard and did not have on the equipment necessary to protect my teeth. As believers, we need to be clothed daily in protective equipment, such as the belt of truth, the shield of faith, and the helmet of salvation to name just a few. This armor of God protects our hearts and minds, just as sports equipment protects our body. And every piece is vital. If we neglect even a seemingly small area of our lives, we can leave ourselves open to things that will hinder our walk with God. Study the armor of God in Ephesians 6:12–17. Put it on every day. Be smart and remember that there are no spare parts—that way you won’t get your teeth knocked out.
