"As if he had said, 'You have no right to reply, that you have not the ability; for all that I require of you is, be strong in the Lord.'" (Calvin) This text identifies our enemies, our assignment, and our armor. We sometimes think of the spiritual and physical worlds as distinct realities with very little overlap. Earth now, heaven later. Paul, on the other hand, sees a deep connection between physical and spiritual realities - in fact, he sees one reality that includes both physical and spiritual aspects. In this world, God's world, we have a simple but difficult command: Stand. Thankfully, we have "the strength of the Lord's might."
