You are walking in a wisdom that is not your own, and that is a beautiful thing to see. When the Holy Spirit impresses on you to hold your peace and let the Lord fight your battles, He is anchoring you in the very heart of the gospel. The victory is already yours, not because you mustered enough restraint, but because Jesus Christ has already overcome the world. That quiet confidence in what He has done is precisely the ground from which you resist the enemy. And you are right: the devil will flee. Not because of the volume of your voice, but because of the authority of the One in whom you stand.
Remember, though, the order that Scripture gives us. First comes submission to God. That is where your strength is renewed. Before you ever open your mouth to resist the devil, you bow your heart before the Lord, acknowledging that His ways are higher and His word is settled forever in heaven. The enemy wants nothing more than to pull you into a war of words, to get you to defend yourself, to make your yes sound like a frantic justification. But you have chosen the better path. Let your yes be yes, and your no be no, and trust that God Himself will perfect everything that concerns you. He is the all-sufficient One, and His word cannot be corrupted by the noise of the world.
There is a peace that flows from being right with God through His Son, a peace that does not depend on the battle going silent around you. It is an inner stillness that comes because the war between your soul and your Maker is over. That is what Jesus secured for you. And now, even when the enemy whispers accusations or stirs up conflict, you can possess a meek and quiet spirit, which is of great value in God’s sight. That does not mean you are passive; it means you are anchored. When you refuse to be irritable or cranky, when you resist the impulse to fight fire with fire, you are displaying the very power of the Spirit. Greater is He that is in you than he that is in the world.
So keep standing on the word. The theories of men will shift, but the Word of God stands forever. Let it be your counselor in the night and your song in the day. When you feel the heat of a verbal confrontation rise, remember that you are not on trial before men but before God, and He sees the sincerity of your heart. He is not asking you to win an argument; He is asking you to trust Him with your reputation and your outcome. As you do, you will see Him scatter your enemies in ways you could never engineer. Rejoice in that. Rejoice that the Lord takes pleasure in the prosperity of His servant, and let your continual refrain be, “Let the Lord be magnified.” He will handle what you have released to Him.
