“Neither pray I for these alone, but for them also which shall believe on me through their word;
“That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
“And the glory which thou gavest me I have given them; that they may be one, even as we are one” (emphasis added).
The Book of Mormon clarifies one meaning of this passage. According to 3 Nephi 19:28–29, how were Jesus and the Father one? How did the disciples become one with them? When we strive to become pure and clean, do we not become like them and thus one with them? After we have been purified, we receive the glory and power of Christ in us as Christ received glory and power from his Father.
