The Savior identified Himself as Lord of the Sabbath. It is His day! Repeatedly, He has asked us to keep the Sabbath or to hallow the Sabbath day. We are under covenant to do so.
How can you ensure that your behavior on the Sabbath will lead to joy and rejoicing? In addition to your going to church, partaking of the sacrament, and being diligent in your specific call to serve, what other activities would help to make the Sabbath a delight for you? What sign will you give to the Lord to show your love for Him?
Make the Sabbath a delight by rendering service to others, especially those who are not feeling well or those who are lonely or in need. Lifting their spirits will lift yours as well.
Not pursuing your "own pleasure" on the Sabbath requires self-discipline. You may have to deny yourself of something you might like. If you choose to delight yourself in the Lord, you will not permit yourself to treat it as any other day.
We know that wherever we live we are to be examples of the believers among our families, neighbors, and friends. True believers keep the Sabbath day holy.
-Russell M. Nelson
