When Joseph and Oliver commissioned and ordained twelve Apostles, there were told they were not actually Apostles until they had obtained their own knowledge of Christ. When one is baptized by water, they are not baptized by fire until a time of God's choosing. When one goes through the veil of the temple, the person does not enter heaven on the other side until they actually fulfill the blessings offered to them in the temple. When one is ordained to the Melchizedek priesthood, he does not actually have that most Holy Priesthood until he proves himself acceptable and God Himself gives it to him.
"For there is not a place found on earth that he may come to and restore again that which was lost unto you, or which he hath taken away, even the fulness of the priesthood....But I command you, all ye my saints, to build a house unto me; and I grant unto you a sufficient time to build a house unto me; and during this time your baptisms shall be acceptable unto me. But behold, at the end of this appointment your baptisms for your dead shall not be acceptable unto me; and if you do not these things at the end of the appointment ye shall be rejected as a church, with your dead, saith the Lord your God." (D&C 124:28, 31-32)
From Passing the Heavenly Gift : "...the place whereon thou standest is holy ground."
When Moses came into God's presence, was redeemed from the fall, and obtained His promise of eternal life, he became the Lord's temple. When we read the Lord's admonition to Moses to "[put] thy shoes from off thy feet, for the place whereon thou standes is holy ground," we tend to put the emphasis on "the place." We should instead put the emphasis on "thou." That is, no matter where Moses stood, having been redeemed from the fall, he always stood on holy ground.
The true temple of God is therefore the redeemed individual. A revelation to Joseph explained:
For man is spirit. The elements are eternal, and spirit and element, inseparably connected, receive a fulness of joy; And when separated, man cannot receive a fulness of joy. The elements are the tabernacle of God; yea, man is the tabernacle of God, even temples; and whatsoever temple is defiled, God shall destroy that temple. (D&C 93:33-35)
"The Apostle Paul put it more simple: "Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?" (1 Cor. 3:16)
(ch 10, p. 281)
"I preached in the grove, on the keys of the kingdom, charity, &c. The keys are certain signs and words by which false spirits and personages may be detected from true, which cannot be revealed to the Elders till the Temple is completed. The rich can only get them in the Temple, the poor may get them on the mountain top as did Moses. The rich cannot be saved without charity, giving to feed the poor when and how God requires, as well as building. There are signs in heaven, earth and hell; the Elders must know them all, to be endowed with power, to finish their work and prevent imposition. The devil knows many signs, but does not know the sign of the Son of Man, or Jesus. No one can truly say he knows God until he has handled something and this can only be in the holiest of holies." (Joseph Smith, HC v. 4, ch. 35)
