As stated before the Lord Jesus Christ know who is of his fold!:)
Brigham Young, writing in Journal and Discourses Volume 7:282 titled Intelligence, wrote the following:
Joseph Smith holds the keys of this last dispensation, and is now engaged behind the vail in the great work of the last days.
I can tell our beloved brother Christians who have slain the Prophets and butchered and otherwise caused the death of thousands of Latter-day Saints, the priests who have thanked God in their prayers and thanksgiving from the pulpit that we have been plundered, driven, and slain, and the deacons under the pulpit, and their brethren and sisters in their closets, who have thanked God, thinking that the Latter-day Saints were wasted away, something that no doubt will mortify them-something that, to say the least, is a matter of deep regret to them-namely, that no man or woman in this dispensation will ever enter into the celestial kingdom of God without the consent of Joseph Smith.
From the day that the Priesthood was taken from the earth to the winding-up scene of all things, every man and woman must have the certificate of Joseph Smith, junior, as a passport to their entrance into the mansion where God and Christ are-I with you and you with me.
I cannot go there without his consent.
He holds the keys of that kingdom for the last dispensation-the keys to rule in the spirit-world; and he rules there triumphantly, for he gained full power and a glorious victory over the power of Satan while he was yet in the flesh, and was a martyr to his religion and to the name of Christ, which gives him a most perfect victory in the spirit-world.
He reigns there as supreme a being in his sphere, capacity, and calling, as God does in heaven.
Many will exclaim-
"Oh, that is very disagreeable!
"It is preposterous!
"We cannot bear the thought!"
But it is true.
If you grow up in the LDS church, you learn, in primary, Sunday school and seminary, many wonderful things that prophets did.
The miracles of Joseph Smith, The Book of Mormon Prophets, and the prophets and apostles in the Bible.
Your expectations build up. You can imagine a modern prophet having the same powers as previous ones. You expect to see miracles as a normal course of things.
When the people in the Book of Mormon found records they couldn't read they brought them to the Prophet and he translated them. When hearing about the Dead Sea Scrolls, you wonder why the Prophet didn't translate them for us.
You wonder why the church used scholars instead of inspiration. Wasn't that the problem with the Bible?
When hearing about Spencer W Kimball's operation for throat cancer, you wonder about the gifts of healing and why we've never heard of our apostles healing people like the apostles in the New Testament.
You wonder about the gifts of discernment over the Hoffman scandal.
You wonder why any doctrine could be unclear in the bible after Joseph Smith retranslated it and why that disclaimer about the bible not being translated correctly was still in the Articles of Ffaith.
You expect the Prophet as a spokesman for God on earth, would say something that God would say to everyone - not just the church. Especially during real troubling times.
You expect the Prophet and the President of the United States to be talking regularly like they did in the Book of Mormon. Either clashing like Abinadi and Noah or collaborating like Moroni and Alma during the wars.
You never expect any Prophet to have lead people astray or to have to apologize or discount the things former Prophets did.
What kind of doubts do YOU have???
