"And behold, I tell you these things that ye may learn wisdom; that ye may learn that when ye are in the service of your fellow beings ye are only in the service of your God...And thus were all equal and they did all labor, every man according to his strength. And they did impart of their substance, every man according to that which he had, to the poor, and the needy, and the sick, and the afflicted."
-Mosiah 2:17, Alma 1:26-27

When we serve each other we are also serving the Lord.
