Not long ago, I asked the question, Who is Him/He who sits on the throne in?
Rev. 4:2 --- "and the One sat on the throne."
Rev. 5:7 --- "Him who sat on the throne".
Rev. 5:1 --- "Him who sat on the throne"
Rev. 5:13 --- "Blessing and glory and power be to Him who sits on the throne, and to the Lamb forever and ever!"
Rev. 6:16 --- "hide us from the face of Him who sits on the throne, and from the wrath of the Lamb!"-
Rev. 7:10 --- "Salvation belong to our God who sits on the throne, and to the Lamb!"
Rev. 21:5-7 --- "Then He who sat on the throne said," --->
It has been revealed to me is that Jesus the Son of man is the One sits on the throne of His glory -> Matt. 19:28, who is the One that said, "He who seen Me has see the FATHER. --- Believe Me that I am in the FATHER, and the FATHER in Me - (John 14:8-11)", who is "the One sat on throne." - (Rev. 4:2).
Rev. 21:5-7 -> He who sat on the throne said to John, "I am the Alpha and the Omega, the Beginning and the End. - Rev. 1:8 -> "I am the Alpha and the Omega, the Beginning and the End," says the Lord, "who is and who was and who is to come, The Almighty." Rev. 1:18 -> "I am He who lives, and was dead, and behold, I am alive forevermore, Amen "
From what is written, I conclude that the Alpha and the Omega is Jesus who is Him/He who sits on the throne, and the Lamb is the One that came and took the scroll/book out of the right hand of Him who sat on the throne, - (Rev. 5:5-7), who had a name written that no one knew except himself" - (Rev. 19:12)
Shortly after Jesus the Alpha and the Omega spoke to John about he/him who overcomes as Jesus overcame in Rev.1:17 to Rev. 3:21, John said, "I wept so much, because no one was found worthy to open and read the scroll/book, but one of the elders said to me, Do not weep --->" - (Rev. 5:1-13)
The reason one of the elders said to John "Do not weep" is that one was found worthy to open and read the scroll/book, and he was also worthy to take the scroll/book out of the right hand of Him who sat on the throne. Knowing that the Alpha and the Omega is Jesus who is Him/He who sits on the throne, then who is the one found worthy to take the scroll/book out of the right hand of Him who sat on the throne?
On 'The Day of the Lord' they will said, "Blessed is he who comes in the name of Him who sits on the throne" - (Matt.23:39), because he was found worthy to take the scroll. Jesus said, "To him who overcomes, I will write on him the name of My God and My new name" - (Rev. 3:12) him who overcomes is the one who had a written that no one knew except himself - (Rev. 19:12), and he is the one found worthy to take the scroll/book out of the right hand of Him who sat on the throne, and also, him who overcomes (Rev. 2:26-29 + Rev. 12:5) is the Lamb who is the King of Kings and Lord of Lords, and Him who sits on the throne is Jesus, The Lord God Almighty of every creature including ALL mankind. - (Rev. 4:8 + 4:11),
