I am grateful for the blessing of having a physical body, which is an amazing gift from our Heavenly Father. Our bodies have over 600 muscles. Many muscles require exercise in order to be in condition to perform our daily activities. We could expend much mental effort reading and learning about our muscles, but if we think this will make them stronger, we will be very disappointed. Our muscles grow only when we use them.

I have come to realize that spiritual gifts behave in the same way. They also need to be exercised to grow. – Juan Pablo Villar, “Exercising Our Spiritual Muscles,” Ensign (CR) May 2019
