Paul ends Ephesians with the clearest call for Christians to go to war in all scripture. Our war, lest anyone should mistake, isn't against people, also known as “flesh and blood”, but against “spiritual forces” (Ephesians 6:12). How do we fight against an unseen enemy? The extended spiritual armor metaphor tells us that our battle is won precisely in putting on the protection God gives us. In fact, every piece of armor to fight is a gift of God including: truth, righteousness, salvation, and the sword of God's Spirit which is the scriptures. Even faith, as we learned earlier in Ephesians, is a gift of God (Ephesians 2:8). So when we fight a powerful, unseen enemy, we take up the weapons given us our more powerful God who dwells in the heavens. From beginning to end, Ephesians is saturated with the grace (charis) of God that gives us more gifts than we know. Thus it should not be surprising that whatever battles we have to face, and here we learn the most important are spiritual battles, we have been given ample weaponry by God for the fight.
