In the “The Battlefield of the Mind” Joyce Meyer lays out the enemy's mission to destroy our faith in Christ. “He begins,” she writes, “by bombarding our mind with a cleverly devised pattern of little nagging thoughts, suspicious, doubts, fears, wonderings, reasonings, and theories. He moves slowly and cautiously... He knows what we like and what we don't like. He knows our insecurities, our weaknesses, and our fears. He knows what bothers us most. He is willing to invest any amount of time it takes to defeat us.”
He is willing to invest whatever time it takes to defeat you! Do you want to defeat him? Are you ready to invest your mustard seed of faith in Jesus Christ, read the Word until it becomes His power in your mind, live obediently, and fight this battle by choosing to believe in God's truth? The mind is where Satan attempts to play his games–to tell his lies–to build his lying strongholds, and destroy the faith that Christ has placed within you. You cannot sit on the sideline and hope it will go away. You cannot cover your ears, and pretend it is not there. That voice can be silenced. But it can only be defeated when you choose to fight with the Word of God and the power of Holy Spirit.
“The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ” (2 Corinthians 10:4,5), NIV). Just as in a battle on a physical battlefield, you want to choose your best ground, and define your terms of combat. In the battlefield of the mind, you also make choices that are advantageous to you. You have the ability to choose doubt or to have faith. You choose to believe the Word or not believe the Word. You choose the power of the Holy Spirit to stand strong against Satan's lies (Ephesians 6:10-17). You choose to place your faith in the Lord's promises instead of those lies. You choose to take captive your thoughts. You must continually practice choosing to believe. What you practice again and again, you learn.
The Holy Spirit will give you the strength to stand strong and believe in His promise instead of believing in the lies of the enemy. When you give all of this to the Lord with thanksgiving in your heart that He will take care of you, you will find His rest and peace in your mind (Philippians 4:6-7). Stand strong in the Lord, and the enemy will be silenced. Don't despair. Stand and continually make your choice. There is deliverance.
