One of the main points of emphasis in our study is that the armor has both offensive and defensive benefits. For instance, the Breastplate of Righteousness provides protection for our vital organs. This protection is necessary when we are under attack, on defense. But, we also need this protection when we are attacking, on offense.
During the class discussion this morning, this question was raised: “Is there an offensive and defensive application for every piece of armor?”
From my studies of the Roman army, and of Ephesians 6, I believe the answer is “yes.” Different pieces may have different primary functions, but I think they are all necessary for both offensive and defensive conflicts.
Maybe answering a question with a question will help make the point: “Which piece of armor would you take off if you were in attack mode, rather than a defensive mode?”
Would you take off your helmet if you were going to attack an enemy formation? Would you leave your shield behind if you were marching on an enemy fortress?
Think about each of the pieces of armor listed by Paul: belt, breastplate, sandals, helmet, shield, sword, and prayer. I think you will find that all of these pieces are equally important whether you are on the attack, or being attacked.
