- “… I believe the Lord meant just what He said, that we should be perfect, as our Father in heaven is perfect. That will not come all at once, but line upon line and precept upon precept, example upon example, and even then not as long as we live in this mortal life, for we will have to go even beyond the grave before we reach that perfection and shall be like God.” Teachings of Presidents of the Church: Joseph Fielding Smith, (2013), 228–39
- D&C 128:15…And now, my dearly beloved brethren and sisters, let me assure you that these are principles in relation to the dead and the living that cannot be lightly passed over, as pertaining to our salvation. For their salvation is necessary and essential to our salvation, as Paul says concerning the fathers—that they without us cannot be made perfect—neither can we without our dead be made perfect.
- “Be ye therefore perfect, even as your Father which is in heaven is perfect [Matthew 5:48.]. I believe the Lord meant just what He said, that we should be perfect, as our Father in heaven is perfect. That will not come all at once, but line upon line and precept upon precept, example upon example, and even then not as long as we live in this mortal life, for we will have to go even beyond the grave before we reach that perfection and shall be like God.” Manual, Teachings, Chapter 18 Living by Every Word That Proceeds from the Mouth of God
