When you are tempted to worry, instead of worrying, set your mind on God and His promises to you. Fill your heart and mind with thoughts of faith, praise, and thanksgiving even in the midst of the trials and adverse circumstances you are facing. Instead of worrying, begin to praise and give thanks unto God for the answer to your need.

You cannot do this in your own limited strength or in the power of your natural mind. Regardless of how strong your will may be, you cannot do this simply by willpower or by determining that you are no longer going to worry or allow yourself to be defeated. You must rise up in the power of the Holy Spirit within you. The battle must be fought and won in the Spirit.

When you recognize that your mind is in turmoil or you are feeling fearful, worried, discouraged, or defeated, take aggressive action. Get on your face before God in prayer and supplication. Go deep into the Spirit and begin to bind the power of the enemy. Draw upon God's strength and the power of the Holy Spirit within you to resist, oppose, and withstand Satan's attack on your mind. Exercise your authority over Satan by taking control over your thoughts and casting out every negative thought, worry, and doubt in the Name of Jesus. Command Satan to take his hands off your mind.

Say to him: “Satan, you have no control over my mind. I command you, in the Name of Jesus, take your hands off my mind! I resist you now in the power of Almighty God that is within me. I reject every negative thought, every fear, doubt, and worry from my mind. It is written, God has not given me a spirit of fear, but of power, love, and a sound mind. I claim the peace of God over my mind now, in the Name of Jesus.”

Satan doesn't give up easily. He will try to bring back worry and doubt into your mind. Every time you sense that you are worried, discouraged, depressed or feel defeated, recognize it as an attack of Satan. Continue to rebuke and resist him in the Name of Jesus. As you continue to do this, he must leave and the thoughts of fear, worry, and unbelief must leave with him. He has no choice. As you actively resist him, he will flee!

Paul said, “And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus” (Philippians 4:7, NIV). The word “guard” in this verse is a military term which means “garrison.” God has promised that as you refuse to worry and present your needs to Him in praise and thanksgiving, He will guard your heart — your thoughts, will, and emotions — as soldiers under military law guard a garrison (constantly watch over it, guard and protect it) so that it remains safe from enemy attack.

I am drawing upon God's strength and the power of the Holy Spirit to resist, oppose, and withstand Satan's attack on my mind.
