Doubt of the right kind -- that is, honest questioning -- leads to faith. Such doubt impels men to inquiry which always opens the door to truth. The scientist in his laboratory, the explorer in distant parts, the prayerful man upon his knees -- these and all inquirers like them find truth. They learn that some things are known, others are not. They cease to doubt.
John A. Widstoe, Evidences and Reconciliations, "Is it wrong to doubt?", Improvement Era writings, compiled by G. Homer Durham
There are two kinds of people in this world; those who accept their doubt as reality and those who doubt but seek to find the answer to resolve that doubt.
I try to be the latter type of person but sometimes lack of motivation does keep me from honestly seeking the truth.
We all have doubts, we all have questions. And sometimes answers to some of those doubts and questions will not come in this life. That shouldn't stop us from seeking those answers though. Life is a nonstop journey of finding the truth in all things. There is always something to learn and discover.
Another point here is the source of those answers to our questions. Consider where or from whom those answers are coming. Why not just ask the Person whose eternal plan, whose gospel this is?
