More than a decade ago, Elder Uchtdorf stood at the pulpit in general conference and gave the Church one of its most quoted lines: doubt your doubts before you doubt your faith. Around that line he built something gentle. Questions are natural, he said. Nearly every member wrestles at some point. Faith can still grow in ground full of doubt, and there is room in the Church for the one who is struggling. But is doubt truly okay? Christianity, in its essence, is one of the most radical religions ever to appear on the earth. We know it is radical because of how the first Christians lived. They went to the lions willingly, when a pinch of incense to an idol would have set them free. When plague swept the empire, pagan families pushed their own sick into the streets and fled. The Christians stayed. They nursed the dying, caught the sickness from the very people they were holding, and died beside them. They gave their entire existence for what they believed. Those people did not have doubt. You do not walk toward a lion with your options open. The idea that doubt is okay did not come from them. It comes from us. Religious doubt is a postmodern, secular habit of mind: hold everything loosely, commit to nothing fully, and go with the flow. James named it long before we did. He that wavereth is like a wave of the sea driven with the wind and tossed. A double minded man is unstable in all his ways. Going with the flow works while the water is calm. Faith is not measured in calm water. Sooner or later the world falls out from under your feet. Life hits you hard. A family member is dying of cancer. Something awful happens in your own life that you never saw coming and cannot undo. In that hour there is no current to drift with. There is only what you are actually standing on. If what you are standing on is doubt, the floor collapses beneath you. Doubt is an interesting thing to discuss in a classroom. It is a terrible thing to stand on at a graveside. I am not saying a believer never meets doubt. We all will, somewhere along the road. Thomas doubted, and the scriptures do not hide it. But the Lord met that doubt with open wounds and a command: Be not faithless, but believing. And Thomas did not stay where he was. He said, My Lord and my God, and tradition states he went all the way to India to a martyr's death. Doubt can be a moment. It cannot be a dwelling. At the end of the day you must have conviction. If you do not have conviction, Christianity is not for you. It is not going to work. And it is not only about you. Think of your children. They learn faith from you, and there is no hiding doubt from a child. None. Children do not read our arguments. They read our posture. Our loyalty. Our commitment. So yes, conviction matters. With Christianity it is a radical conviction. The question was never whether the doctrine seems reasonable or the ward feels warm. The question is whether I am willing to sacrifice everything for the church. Whether I will pick up my own cross in my own life. If any man will come after me, let him deny himself, and take up his cross daily, and follow me. That is the true meaning of Christianity.
