President Uchtdorf recently taught that our activities should not be inspired by any flashy trend or interest of the moment. He says, "Otherwise, they can distract our efforts, dilute our energy, and get us caught in our own hobbies, spiritual or temporal, that are not the center of discipleship."
So what exactly is a spiritual hobby?
Here's an example that will hopefully make sense:
Jessica reads her scriptures for an hour everyday at 6:00 AM. One morning she gets a phone call at 5:45 AM. One of Jessica's friends has been seriously hurt and needs her assistance to get to the hospital. She considers going to help but remembers that she has to study so she decides to stay home and read instead.
Now, this is kind of an extreme example but hopefully it gets the point across. I would encourage each of us to take a look at the activities that occupy our lives. Ask yourself, "Is this activity worth my time?"
