Paul wrote to the Ephesians that they were to “put on the whole armor of God.” Wanting Christians to be fully prepared for battle, he writes about the belt of truth, the breastplate of righteousness, the shoes of the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit. But did you notice what he missed? There is no armor for the back. Paul describes most of the armor a Roman soldier would wear, but he left out the backplate.
Some have suggested that he left it out because the only ones who can harm you from behind are your friends, other members of your own army. We still use phrases like “stab you in the back,” “backbiting,” and “got your back.” Perhaps we are to enter the battle so sure of our fellow Christians that we don’t need any back armor.
Or maybe Paul wants to stress that this is a battle we need to meet head on. We are warring against Satan and his powers, both earthly and spiritual, and we dare not turn our back on him. We trust so much in our commander that we know we will never have to run.
Either way, we are engaged in a battle we cannot afford to lose. We don’t have a choice. Christians are soldiers, warriors, and we are in the fight of our lives.
