Having the means to attend the temple—if only once in a lifetime—brings hope and joy to countless saints. Living prohibitive distances from the nearest temple need not prevent worthy members and families from receiving the eternal blessings of salvation that can be received only in the temple.
There are likely to be many more temples constructed in fulfilling the prophecies that "temples will dot the earth." In the meantime, imagine the joy you can feel in knowing that you have helped just one couple, or one family, receive the blessings that allow them to take the necessary steps toward becoming an eternal family. Then contemplate the joy—the great joy—they will experience because someone they do not know, but with whom they share a common testimony, was willing to sacrifice enough to help a fellow saint enjoy the blessings of eternity. Surely, there can be no greater joy.
