"Death and life are in the power of the tongue" (Prov. 18:21).
You have all the power you need to get the victory you've been believing for. You just have to speak it out of your mouth.
What's coming out of your mouth today? Are you praying one way and then speaking doubt and unbelief? Are you confessing, "My God shall supply all my needs according to his riches in glory by Christ Jesus" (Phil. 4:19), and an hour later saying, "We don't have enough to pay our bills. We're never going to get out of debt!"?
What are you saying? Whatever is in your heart in abundance is going to come out of your mouth. If you really don't believe God can heal your illness, then your unbelief is going to manifest out of your mouth.
