“I Am the Spirit of Truth”
Doctrine and Covenants 93:21–28
21 And now, verily I say unto you, I was in the beginning with the Father, and am the Firstborn;
22 And all those who are begotten through me are partakers of the glory of the same, and are the church of the Firstborn.
23 Ye were also in the beginning with the Father; that which is Spirit, even the Spirit of truth;
24 And truth is knowledge of things as they are, and as they were, and as they are to come;
25 And whatsoever is more or less than this is the spirit of that wicked one who was a liar from the beginning.
26 The Spirit of truth is of God. I am the Spirit of truth, and John bore record of me, saying: He received a fulness of truth, yea, even of all truth;
27 And no man receiveth a fulness unless he keepeth his commandments.
28 He that keepeth his commandments receiveth truth and light, until he is glorified in truth and knoweth all things.
The Prophet Joseph Smith said:
“God has created man with a mind capable of instruction, and a faculty which may be enlarged in proportion to the heed and diligence given to the light communicated from heaven to the intellect; and that the nearer man approaches perfection, the clearer are his views, and the greater his enjoyments, till he has overcome the evils of his life and lost every desire for sin; and like the ancients, arrives at that point of faith where he is wrapped in the power and glory of his Maker, and is caught up to dwell with Him. But we consider that this is a station to which no man ever arrived in a moment.”
