As I've grown older, I've considered various actions on if they are things that can bring my closer to my Heavenly Father and to my Redeemer Jesus Christ. Some things are a permanent action, like going to Church, and partaking of the Sacrament (or to Conference if it happens to be one of those Sundays). Some times I attend Firesides where I learn more about the Savior and His Gospel and how I can better live it. When "in season," I attend my choir rehearsals (which is one of my favorite ways to spend the Sabbath--singing about my Savior). I visit friends and family. I visit with the sisters I have been asked to help and be their friend. I like to do my Family History if I can find the time.
I loved watching Church videos when I was growing up. I have a very tiny collection now compared to what our family had, but I still enjoy watching what I own. When I was older, I added some period dramas (like Austen movies) to the mix, because they are a calming influence. They are enjoyable to watch with others. They are great studies of human nature and behavior (yeah, I know, I'm a nerd). I often am crocheting or doing something else while the movie is on in the background. It is a break from the regular routine of my week. When I choose a movie for my Sabbath, I personally evaluate how it will make me feel and think on that holy day. In that choice, it is as I said before a personal thing, and my own way to show my Savior how I regard Him and His day. In my own personal standards, I feel like I stumble occasionally in this area, and perhaps in other actions I've chosen to do on this day. But every Sabbath I try to make my actions consistent with what I feel would be full of the most respect and love for my Redeemer.
