“The Spirit stoppeth mine utterance” Wisdom often dictates that we do not tell all we know. Certainly God has not told us all that he knows.
The knowledge of heaven is given “line upon line, precept upon precept, here a little and there a little” (2 Nephi 28:30).
In the economy of God there is a time and place for all things. Ours is to proclaim that portion of the gospel that the Spirit dictates appropriate (D&C 71:1).
“Spirit Stoppeth Mine Utterance”
As Joseph Smith concluded the writing of the revelation on the degrees of glory he observed: “Great and marvelous are the works of the Lord, and the mysteries of his kingdom which he showed unto us, which surpass all understanding in glory, and in might, and in dominion; which he [God] commanded us we should not write while we were yet in the Spirit, and are not lawful for man to utter; neither is man capable to make them known, for they are only to be seen and understood by the power of the Holy Spirit, which God bestows on those who love him, and purify themselves before him; to whom he grants this privilege of seeing and knowing for themselves.” (D&C 76:114-17.)
