We lose our life by serving and lifting others.

By so doing we experience the only true and lasting happiness. Service is not something we endure on this earth so we can earn the right to live in the celestial kingdom. Service is the very fiber of which an exalted life in the celestial kingdom is made. Knowing that service is what gives our Father in Heaven fulfillment, and knowing that we want to be where He is and as He is, why must we be commanded to serve one another? Oh, for the glorious day when these things will come naturally because of the purity of our hearts. In that day there will be no need for a commandment, because we will have experienced for ourselves that we are truly happy only when we are engaged in unselfish service.
