The pure doctrine of Christ is powerful... it changes the life of everyone who understands it and seeks to implement it in his or her life. The doctrine of Christ helps us find and stay on the covenant path. Staying on that narrow but well-defined path will ultimately qualify us to receive all that God has.
Elder Ulisses Soares, worldwide missionary devotional, January 11, 2022
I'm sure we don't comprehend how powerful the doctrine of Christ is. We can't fathom it. And it's so simple to understand, at least the basics are. All we have to do is internalize it. The more are exposed to it, the more we internalize it.
That's it. Just test that theory. See how your life changes for the better. Trials may not disappear, but our ability to endure them will be strengthened.
