Revelation 4

As a door was opened for John to look into heaven, John records -

"And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne."  (New Testament | Revelation 4:2)

Obviously, as one reads this and the next chapter, the "One" who sat on the throne, was God, our Eternal Father in Heaven.  After making an attempt to describe the "One", he also saw -

"...round about the throne were four and twenty seats: and upon the seats I saw four and twenty elders sitting, clothed in white raiment; and they had on their heads crowns of gold."  (New Testament | Revelation 4:4)

Joseph Smith correctly translated

"JST Rev. 4:4 And in the midst of the throne were four and twenty seats..."  (New Testament:Revelation 4:4)

It becomes clear that His throne extended much farther than we perceive a regular single person throne.  Being in the midst of throne wearing crowns of Gold, it is apparent that these elders had received their exaltation, were kings,  and were "joint-heirs" of with Christ.  The Prophet Joseph Smith answered -

"...We are to understand that these elders whom John saw, were elders who had been faithful in the work of the ministry and were dead; who belonged to the cseven churches, and were then in the paradise of God."  (Doctrine and Covenants | Section 77:5)

But even though they were joint-heirs, kings of kingdoms, it was very clear -

"The four and twenty elders fall down before him that sat on the throne, and worship him that liveth for ever and ever, and cast their crowns before the throne, saying,
11 Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created."  (New Testament | Revelation 4:10 - 11)

No matter what the reward to those exalted, He will forever be our Father and will preside over us.  We will worship Him forever.  John also saw -

"...and in the midst of the throne, and round about the throne, were four beasts full of eyes before and behind.
7 And the first beast was like a lion, and the second beast like a calf, and the third beast had a face as a man, and the fourth beast was like a flying eagle.
8 And the four beasts had each of them six wings about him; and they were full of eyes within: and they rest not day and night, saying, Holy, holy, holy, Lord God Almighty, which was, and is, and is to come."  (New Testament | Revelation 4:6 - 8)

Of such, the Prophet also explained that -

"They are figurative expressions, used by the Revelator, John, in describing heaven, the paradise of God, the happiness of man, and of beasts, and of creeping things, and of the fowls of the air; that which is spiritual being in the likeness of that which is temporal; and that which is temporal in the likeness of that which is spiritual; the spirit of man in the likeness of his person, as also the spirit of the beast, and every other creature which God has created."  (Doctrine and Covenants | Section 77:2)

That -

"...They are limited to four individual beasts, which were shown to John, to represent the glory of the classes of beings in their destined order or sphere of creation, in the enjoyment of their eternal felicity."  (Doctrine and Covenants | Section 77:3)

And that -

"Their eyes are a representation of light and knowledge, that is, they are full of knowledge; and their wings are a representation of power, to move, to act, etc."  (Doctrine and Covenants | Section 77:4)
