When I am running and my legs (or any other body part) hurt, I immediately tell myself, "this discomfort is what is changing my body. This is why I am doing it."
Recently I have learned that the pain of trials is the same thing. Heavenly Father uses trials to help us stretch and grow and become more like our Savior, Jesus Christ. Without the pain we would not have that opportunity.
I know I don't speak spiritually often on this blog, but I felt that this lesson in running is worth sharing.
