The fourteenth and final installment in our study through the book of Ephesians providentially took place on Memorial Day, where Americans across the world can pause and consider the dedication and courage of so many men and women who have sacrificed their lives to fight for what they believed was worth the cost. This is the very fight Paul opens our eyes to in his concluding words for the Ephesian church. Not a fight against an invading political power, or a dangerous ideology as has been the case in US history; rather, Paul turns our attention to the real war being waged: a spiritual war in our own back yards, our own church buildings, in our own hearts. Everything Paul says in this letter all builds to this one call to action: Never let down your guard.
