3. Testimony of John the Apostle Concerning Christ's Development in
Knowledge and Grace.--In a modern revelation, Jesus the Christ has
confirmed the record of John the apostle, which record appears but in
part in our compilation of ancient scriptures. John thus attests the
actuality of natural development in the growth of Jesus from childhood
to maturity: "And I, John, saw that he received not of the fullness at
the first, but received grace for grace; and he received not of the
fullness at first, but continued from grace to grace, until he received
a fullness; and thus he was called the Son of God, because he received
not of the fullness at the first." (Doc. and Cov. 93:12-14).
Notwithstanding this graded course of growth and development after His
birth in the flesh, Jesus Christ had been associated with the Father
from the beginning, as is set forth in the revelation cited. We read
therein: "And he [John] bore record, saying, I saw his glory that he was
in the beginning before the world was; therefore in the beginning the
Word was, for he was the Word, even the messenger of salvation, the
light and the Redeemer of the world; the Spirit of truth, who came into
the world, because the world was made by him, and in him was the life of
men and the light of men. The worlds were made by him: men were made by
him: all things were made by him, and through him, and of him. And I,
John, bear record that I beheld his glory, as the glory of the Only
Begotten of the Father, full of grace and truth, even the Spirit of
truth, which came and dwelt in the flesh, and dwelt among us" (verses
7-11).

4. Missing Scripture.--Matthew's commentary on the abode of Joseph, Mary
and Jesus at Nazareth, "and he came and dwelt in a city called Nazareth:
that it might be fulfilled which was spoken by the prophets, he shall be
called a Nazarene" (2:23), with the fact that no such saying of the
prophets is found in any of the books contained in the Bible, suggests
the certainty of lost scripture. Those who oppose the doctrine of
continual revelation between God and His Church, on the ground that the
Bible is complete as a collection of sacred scriptures, and that alleged
revelation not found therein must therefore be spurious, may profitably
take note of the many books not included in the Bible, yet mentioned
therein, generally in such a way as to leave no doubt that they
