Summary: The devil loves to make a playground out of people’s minds and imaginations.
Mark 11:23 Works for the Devil Too!
For verily I say unto you, That whosoever shall say
unto this mountain, Be thou removed, and be thou cast into the sea;
and shall not doubt in his heart, but shall believe
that those things which he saith shall come to pass;
he shall have whatsoever he saith.
The devil loves to make a playground out of people’s minds and imaginations. He delights in filling their perceptions and senses with illusions that captivate them, paralyze them, and ultimately destroy them. How can believers avoid falling victim to the devil’s attacks? They must make a spiritual and mental decision to take charge of every thought that enters their minds!
Taking your thoughts captive is going to require determination and energy. Once you made the decision to do it, you still have to stick with that decision. If you’re not really committed to seizing every thought the devil tries to inject into your mind and emotions, he’ll be back to strike you again and again. And if you don’t stop the enemy’s thoughts from invading your mind, it won’t be long until your faith begins to empower those thoughts and they become a bona fide reality in your life!
Mark 11:23 is a powerful verse about faith and confession that believers claim and use around the world. But the principle in this verse works both in a positive and negative sense - or to put it another way, this principle works both in the realm of God and in the realm of the devil.
Mark 11:23 says, "For verily I say unto you, that whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith." According to what Jesus taught in this verse, you can bring to pass whatsoever you say and believe in your heart.
Did you notice that Jesus said if a person confesses something "and shall not doubt in his heart" - in other words, if he believes the words he is speaking with his mouth - he will have exactly what he says. The word "doubt" is from the Greek word diakrinomai, which means to hesitate, to waver, to doubt, or to differ. In context, Jesus is saying that when a person’s heart doesn’t differ from what his mouth is saying, the combination of his heart and mouth in agreement will always make things happen!
I call this concept "the heart-mouth connection." For instance, if you believe in your heart that Jesus purchased your healing, and you put your heartfelt faith together with the confession of your mouth, you can literally bring that healing into manifestation in your physical body.
Creative power is released when the heart and mouth get into agreement! That is why you must be careful about what you believe in your heart and say with your mouth, because when your heart and mouth get "in sync" with each other, it literally makes things come to pass!
This heart-mouth combination works on both the positive and negative side of life. It can bring about the manifestation of healing in your body, salvation to your family, prosperity to your business, and growth to your local church. But the devil also knows how to use this principle against you!
The enemy knows if he can fill your mind and heart with lies that you believe and then coax you into confessing those lies with your mouth, you will make those evil images come to pass in your life! That is exactly why the devil wants to fill your mind with lies and accusations. That’s why he paints so vividly on the "movie screen" in your mind. That’s why he assaults your mind and emotions again and again. He knows he just has to get you to embrace these lies and to start believing them.
Once you do that, you’ll soon start speaking those lies out of your mouth. And if you start speaking them with your mouth, it will only be a matter of time until they become your reality. Jesus said, "...out of the abundance of the heart the mouth speaketh" (Matthew 12:34). So according to Jesus, whatever is in your heart is eventually going to come out of your mouth!
Because great power is released when your heart and mouth start working together, it’s extremely important that you put the right things into your heart. Mark 11:23 promises that whatever you believe in your heart and say with your mouth will come to pass. But as I said before, it doesn’t just apply to Bible verses; it applies to anything you believe in your heart and say with your mouth. So if the devil can get you to believe and say wrong things, your own heart and mouth will cause those killer confessions to come to pass.
