“The Prophet On The Second Coming Of The Christ.
The question has been asked, can a person not belonging to the Church bring a member before the high council for trial? I answer, No. If I had not actually got into this work and been called of God, I would back out. But I cannot back out: I have no doubt of the truth. Were I going to prophesy, I would say the end [of the world] would not come in 1844, 5, or 6, or in forty years. There are those of the rising generation who shall not taste death till Christ comes.
I was once praying earnestly upon this subject, and a voice said unto me, “My son, if thou livest until thou art eighty-five years of age, thou shalt see the face of the Son of Man.” I was left to draw my own conclusions concerning this; and I took the liberty to conclude that if I did live to that time, He would make His appearance. But I do not say whether He will make his appearance or I shall go where He is. I prophesy in the name of the Lord God, and let it be written—the Son of Man will not come in the clouds of heaven till I am eighty-five years old. Then read the 14th chapter of Revelation, 6th and 7th verses—”And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, saying with a loud voice, Fear God and give glory to Him, for the hour of His judgment is come.” And Hosea, 6th chapter, After two days, etc.,—2,520 years; which brings it to 1890. The coming of the Son of Man never will be—never can be till the judgments spoken of for this hour are poured out: which judgments are commenced. Paul says, “Ye are the children of the light, and not of the darkness, that that day should overtake you as a thief in the night.” It is not the design of the Almighty to come upon the earth and crush it and grind it to powder, but he will reveal it to His servants the prophets.”
