Learn to expect, not to doubt. In so doing you bring everything into the realm of possibility. This does not mean that by believing you are necessarily going to get everything you want or think you want. Perhaps that would not be good for you. When you put your trust in God, He guides your mind so that you do not want things that are not good for you or that are inharmonious with God’s will. But it does definitely mean that when you learn to believe, then that which has seemingly been impossible moves into the area of the possible. Every great thing at last becomes for you a possibility.
