D&C 4

To the father of the Prophet Joseph Smith as he sought he mind an will of the Lord concerning him, the Lord revealed -

"NOW behold, a marvelous work is about to come forth among the children of men.
2 Therefore, O ye that embark in the service of God, see that ye serve him with all your heart, might, mind and strength, that ye may stand blameless before God at the last day." (Doctrine and Covenants Section 4:1 - 2)

The words "O ye that embark" make it apparent that this revelation was not given to Joseph Smith, Sr. alone, but to all that embark in the service of God. Concerning this revelation, Joseph Fielding Smith wrote -

“it contains sufficient counsel and instruction for a lifetime of study. No one has yet mastered it. It was not intended as a personal revelation to Joseph Smith, but to be of benefit to all who desire to embark in the service of God. It is a revelation to each member of the Church, especially to all who hold the Priesthood. Perhaps there is no other revelation in all our scriptures that embodies greater instruction pertaining to the manner of qualification of members of the Church for the service of God, and in such condensed form than
this revelation. It is as broad, as high and as deep as eternity. No elder of the Church is qualified to teach in the Church, or carry the message of Salvation to the world, until he has absorbed, in part at least, this heaven-sent instruction.” (Church History and Modern Revelation, 1:35.)

I think the very words -

"...a marvelous work is about to come forth among the children of men..." (Doctrine and Covenants Section 4:1)

...would be very gutsy to say to a father or the world had it been a fabricated statement. I know it wasn't, but the truth. I am mindful that for anyone -

"...faith, hope, charity and love, with an eye single to the glory of God, qualify him for the work." (Doctrine and Covenants Section 4:5)

In closing the Lord provides this constant reminder to all that are called to service in the kingdom -

"Remember faith, virtue, knowledge, temperance, patience, brotherly kindness, godliness, charity, humility, diligence.
7 Ask, and ye shall receive; knock, and it shall be opened unto you." (Doctrine and Covenants Section 4:6 - 7)
