The same priesthood power that created worlds, galaxies, and the universe can and should be part of our lives to succor, strengthen, and bless our families, our friends, and our neighbors—in other words, to do the things that the Savior would do if He were ministering among us today.
And the primary purpose of this priesthood power is to bless, sanctify, and purify us so we can live together with our families in the presence of our heavenly parents, bound by priesthood sealings, participating in the marvelous work of God and Jesus Christ in forever expanding Their light and glory.
