The words in your mind must be in agreement with the words in your mouth in order for faith to be effective. Think about, the word of God says you are healed. You begin to say, I am healed. Your mind though, because of the fall, wants to gravitate back to the sense realm: the way you feel, the way things appear, the way of sadness, the way of sorrow. The conversation in your head, can nullify, negate, short circuit, disconnect, and cut off your faith, which in turn, stops the power of the word of God that you are speaking. That’s why Paul admonished the church to cast down imaginations and every high thing that would lift itself up against the word of God, and bring into captivity every thought to the obedience of Christ.
That takes a diligent effort that many people have been willing to have. By this, they received and maintained their healing. They have been able to receive and maintain other things as well, like great protection. By standing on the word of God, in the name of Jesus, by the blood of the Lamb, you shut the door on disasters and calamities. Also remember, the Lord would never ask you to do something that he wouldn’t help you accomplish. That is why Grace was given to you.
Speak the word of God in faith and control your mind to speak the word on the inside. Let every imagination and thought affirm what you believe. Then join the ranks of those who know their God and do great exploits. ….but the people who know their God shall be strong, and carry out great exploits Daniel 11:32
2 Corinthians 10:5
5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ
