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. (Mark 11:23)
Notice that this scripture says, "shall not doubt in his heart." It never said a word about doubting in his head. You see, faith will work in your heart with doubt in your head. You can have doubt in your head, because the devil has access to our physical senses.
He is the god of this world, and he can bring doubt to you. If you see that things are not working out right - maybe your body doesn't feel well - your mind will begin to doubt that you're healed.
What must you do? Hold yourself in the arena of faith by casting down negative thoughts and by believing with the inward man.
Proverbs 3:5 says, "Trust in the Lord with all thine heart; and lean not unto thine own understanding." Don't lean on what your head tells you.
Faith will work in your heart with doubt in your head.
I know from my own personal experience that my head fought me all the way concerning some of the greatest things that have ever happened to me in life. My head said, "It won't work. It's not so. You don't have it." But I refused to entertain those thoughts. I refused to listen to my head. On the inside of me, I held steady.
All kinds of thoughts were flying through my head - faster than machine gun bullets can fly! Thoughts went through my head, such as, "You've messed up this time. You've made a fool of yourself. That's not going to work."
Yes, I had doubt in my head, but I didn't lean to my own understanding. I trusted the Lord with all my heart, and He brought it to pass. Now if I had given in to those thoughts and listened to my head, I would have been defeated.
Confession: I can have doubt in my head, but still have faith in my heart. I follow my heart. I don't lean unto my own understanding. I trust the Lord with all my heart to bring His Word to pass in my life.
