"So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it." (Isaiah 55:11)
Did you know that the battleground for the problem you're facing right now is in your mind and on your lips? If you'llhit the devil with the Word and cast the care of the situation over on God, you'll win.
Let me warn you though, hanging onto the Word isn't always easy. The devil knows that if he doesn't steal it from you, you'll use it to enforce his defeat.
So don't be surprised if he sends an evil spirit to exalt itself against the Word of God. If you're sick, he may begin to tell you, "You're not healed. You know that healing's not for today. Even if it were, it wouldn't work for you. It might work for somebody else but not you."
If he starts to tell you that kind of thing, don't buy it! Don't start worrying around about it and thinking, "Oh my, I'm afraid I'm not going to get healed. I sure don't feel healed. Why, I'm probably going to just get worse and worse...."
Remember this: It's the Word that does the work, not the one holding onto it. It'll work for anybody who'll put it to work. It'll work for you just like it worked for Jesus when He walked the earth.
He told Satan, "It is written!" No matter what the devil tries to tell you, refuse to let go of the Word. Tell him what is written concerning your situation. Let the Word fight its own fight. It'll whip the devil every time.
