Plug Into the Power

Finally, my brethren, be strong in the Lord, and in the power of his might. (Ephesians 6:10)

When someone uses the word “finally” in a letter, it shows they believe this is a crucial point they need to emphasize. Paul saved his strongest command for the end of his letter. After six chapters of wisdom, guidance on healthy relationships, Biblical doctrine, and discipline, he concludes with this: “Be strong in the Lord.” The Greek word for "strong" is kratos, which means dominion, vigor, and unstoppable force.

It’s not just about muscles; it refers to strength expressed through victory. This power works alongside His “might” or ischus, representing God's forcefulness and ability. In other words, when you tap into God's power that He has given you, you aren’t just boosting your stamina—you’re actually drawing from His own supply. If you’ve ever thought, “I’m just too tired,” what Paul wrote is for you. You didn’t miss it, or you aren’t being “attacked” differently than believers worldwide; you’re simply disconnected from your source of power. Our strength fails when our prayers run dry.

Paul wasn’t suggesting that believers should just walk in this strength; he’s issuing an imperative command. In Greek, “be strong” is endunamō, meaning to empower oneself, to make oneself strong. The understood subject in that phrase is you. That means God has given you everything needed to do this, but He won’t force you—it’s up to you. Paul was telling us that weakness isn’t a condition of our spirit; it’s a choice of our focus.

Practical Application

It’s crucial to recognize the signs of spiritual depletion. When you feel more irritable, apathetic, or overwhelmed by fear, see these as low-battery signals. Recharge by worshiping, declaring the Word, and praying in the Spirit. A dead phone isn’t broken; it’s just unplugged. Your spirit works the same way.
