“Young men, I admonish you to prepare for service as a missionary. Keep yourselves clean and pure and worthy to represent the Lord. Maintain your health and strength … ,” said President Thomas S. Monson during the opening session of the 180th Semiannual General Conference. “A word to you young sisters: while you do not have the same priesthood responsibility as do the young men to serve as full-time missionaries, you also make a valuable contribution as missionaries, and we welcome your service. And now to you mature brothers and sisters: we need many, many more senior couples. … There are few times in your lives when you will enjoy the sweet spirit and satisfaction that come from giving full-time service together in the work of the Master.”
