Take baby steps in your situation and speak it out. Start with small things and build up your confidence in Christ. Book mark it in your mind (or write it down) and when you face bigger obstacles (which you will in life) you will be ready and God will help you. If a former wimp like me can do it you can do. God is no respecter of persons. I have seen mountains move: chronic pain, storms, migraine headaches, car troubles, cysts (to name a few). You can do it just remember if you are a believer in Christ, he put that power in you already. If you ask him for something he already gave you then you are a double-minded person. How is he going to answer that? It just shows that we don’t understand the promises; so, they won’t work. The Bible means what it says and says it the way it does for a reason. This is how the Kingdom works.
Just thank him for his goodness and for the promise and then speak it out. It may be shaky at first, but God will help you if you let him. So, move that mountain even if it’s one baby step at a time. And refuse to quit and don’t take no for an answer and you will eventually see it come to pass.
In Matthew 17:20 Jesus said, “if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.”
