Doubt Not, But Be Believing
Sometimes when things appear to be going all wrong, even when you are living righteously, it will work together for your good in the long run.
"I have a friend who bought a business. A short time later he suffered catastrophic reverses and there just didn't seem to be any way out for him. Finally it got so bad that he couldn't sleep, so for a period of time he followed the practice of getting up about three o'clock in the morning and going to the office. There, with a paper and a pen, he would ponder and pray and write down every idea that came to him as a possible solution or contributions to the solution of his problem.
It wasn't long before he had several possible directions in which he could go, and it wasn't much longer than that until he had chosen the best of them. But he had earned an extra bonus. His notes showed, after he went over them, that he had discovered many hidden resources he had never noticed before. He came away more independent and successful than he would ever have been if he hadn't suffered those reverses.
There is a lesson in this experience. A year or two later he was called to preside over a mission overseas. His business was so independent and so well set up that when he came back he didn't return to it. He now has someone else managing it, and has been able to give virtually all his time to the blessing of others."
Boyd K. Packer, Teach Ye Diligently, p. 204-5
Have Faith, never Doubting.
"Doubt not, but be believing...
Mormon 9:27
"...where doubt and uncertainty are there faith is not, nor can it be. For doubt and faith do not exist in the same person at the same time; so that persons whose minds are under doubts and fears cannot have unshaken confidence; and where unshaken confidence is not there faith is weak."
Joseph Smith, Lectures on Faith, p. 59-60
"Look unto me in every thought; doubt not, fear not."
D&C 6:36
