See, most people focus on what didn't happen, rather than what did happen. Focus on what did happen, and thank God, and let it grow in your life; rather than focusing on what didn't happen.
When I was trained, I trained in physics and science and maths, so my whole orientation was what didn't happen, so I couldn't move in these kinds of things at all, until I changed and said: well what has happened?
Has anything happened? If there was a little improvement - something has started. Thank God, and keep moving, and believe God for the full healing to take place.
