For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strongholds. (2 Corinthians 10:4)
In man there is a spirit, the part of man that is the receiver for spiritual things. Mark Hankins
Where are strongholds located? Paul said they are in your mind. He said to bring every thought into captivity. That means you must get control of your mind and your body. You must do that daily through the weapons of your warfare.
What are the weapons of your warfare? Get the Word of God and begin feeding on it. Your spirit is hungry for God. Your flesh may be hungry for chicken fried steak or apple pie, but your spirit is hungry for God. The Word is full of supernatural life and power.
Start speaking, “Satan, the blood of Jesus is against you.” Start talking about the name of Jesus. Start praying in the Holy Spirit. The devil cannot tell what you are saying when you pray in other tongues. Your spirit (the part of you that is born again) gets edified and rises up in response to faith-filled words.
Confession: My spirit is born again. Satan the blood of Jesus is against you. My old man, the old person I used to be, was crucified with Christ and I do not serves in. I am dead to sin and alive unto God!
