Our mission as a family is to obtain Eternal Life (as individuals and as a family) with God the Eternal Father and His Eternal Son, Jesus Christ (see John 17:3, Rom 6:23, D&C 14:7, and Moses 1:39).
We do this by keeping the commandments of God (see D&C 93:1-3, 19-20 and 26-28), becoming clean through the Atonement of Jesus Christ (see Hel. 3:35, 3 Ne 27:20, D&C 20:31. D&C 76:41 and Moses 6:59-60), and by remaining on the "...strait and narrow path" as described in 2 Nephi 31:17-21.
We work together as a family and support each other in obtaining this goal.
