Your soul can’t protect your soul.
You have to be strengthened by the Lord and His power. The enemies you need protection from are spirits. You are, too. His Spirit empowers your spirit to overcome those spirits.
Maybe the armor you need to put on is Him. He is the Truth, the Righteousness, the Covering. Your soul just needs to keep making the decision to allow Him to be your safe place. You can’t muster up enough strength to overpower the rulers and powers that are opposed to His work in the earth by being tough. You have to be in the Spirit (Ephesians 6:18).
You can’t even stop smoking tobacco without outside help. BUT – you have Outside Help inside! Let Him fight for you and through you.
Your soul (mind, will, emotions) just harbors strongholds that give your enemies strength if you don’t submit it to the Spirit of God. Fear, bitterness, unforgiveness, pride, addictions, and more – these are built by and in your soul, and will prevent you from victory by being armor that is against the Spirit of Jesus working to change and use and protect you!
Be transformed by the renewing of your mind, and be empowered to both effective offense and defense by the Spirit of God in you and on you. Stand – by His strength and His wisdom and His righteousness.
