“The Testimony Which Ye Have Borne Is Recorded in Heaven”
Doctrine and Covenants 62:3
3 Nevertheless, ye are blessed, for the testimony which ye have borne is recorded in heaven for the angels to look upon; and they rejoice over you, and your sins are forgiven you.
Elder Hyrum M. Smith and Janne M. Sjödahl wrote:
“The elders are blessed, for the testimony they had borne had been recorded in heaven for the angels to look upon. St. Peter uses a similar expression [see 1 Peter 1:12]. He teaches us that prophets have diligently searched to find out the time indicated by the Spirit of Christ, when it testified of His sufferings and the glory that should follow. These things, he says, ‘angels desire to look into.’ In this revelation [D&C 62] we are told that angels are scrutinizing the records kept of the testimonies of the elders, and that they rejoice over the witnesses. It appears from this that the ministry on earth has its effects beyond the veil as well as on this side. An elder who bears his faithful testimony to the truth does not know how far-reaching the result may be, though his visible audience may consist of but few.”
