So faith comes from hearing, and hearing by the word of Christ. (Romans 10:17 NASB)
Dr. Creflo Dollar writes in Breaking Out of Trouble:
The reciprocal of that statement is that fear comes by hearing the words of the devil. The devil wants you to hear his words. Because he is the god of the world system, he wants you to hear the words that come from the world system. He wants you to fill your heart with his words so you will operate in fear, which is inverted faith.
Pay close attention to what I’m saying. To walk in fear is to walk in faith. If you fear cancer, what you’re actually doing is having faith and confidence in the ability of cancer to kill you. If you fear losing your job because of a wrong report about you, you’re actually having faith and confidence in the ability of that wrong report to cause you to lose your job. If you fear being mugged when you go to the ATM machine at night, you have faith and confidence in the ability of that mugger to attack and rob you. When you operate in fear, you’re operation in the faith and confidence that the thing you fear has the ability to destroy you.
So you have to reverse the process. Instead of having fear that the devil can do a certain thing in your life, you must have faith in the Word of God. Your faith is a force which will produce whatever is in your heart. Whatever is in your heart will motivate you to give room for either God or the devil to bring that thing to pass. I know it sounds strange, but fear is the faith of the devil. Fear is what the devil needs in order to bring certain things to pass in your life.
Where is there fear in your life? Wherever the fear is in your life, you must move it, because if you don’t move it, you have left a door open for the devil to say, “I have the right to bring the thing that he fears to pass.”
Be self-controlled and alert. Your enemy the devil prowls around like a roaring lion looking for someone to devour. (1 Peter 5:8 NIV)
