A mission is not just a casual thing-it is not an alternative program in the Church. Neither is a mission a matter of choice any more than tithing is a choice, any more than sacrament meeting is a choice, any more than the Word of Wisdom is a choice. Of course, we have our free agency, and the Lord has given us choices. We can do as we please. We can go on a mission or we can remain home. But every normal young man is as much obligated to go on a mission as he is to pay his tithing, attend his meetings, keep the Sabbath day holy, and keep his life spotless and clean.
