Being thankful during suffering, I'm gonna say, is maybe one of the spiritual keys to how to walk through a time of trial. And if you're asking, "Well how can I be thankful?" Very simply, it's a decision. It is an act of the will to look up to your Heavenly Father and to thank him for every circumstance. You still have water, you still have food, you still have air to breathe, you still have land to walk upon. There's always much to be thankful for, and it is the best thing for your soul, when you're in the midst of a difficult trial.
