The Servants of God
REVELATION 22:4-5
The servants of God shall see His face, and His name shall be on their foreheads, indicating their complete subjection to the dominion of God over their persons. These will be the inhabitants of the New Jerusalem, in their spiritual bodies, those out of humanity who throughout the millennia will have been justified and gone through the first resurrection. These will serve God and will reign forever and ever.
The millennial age and the perfect age, between which the earth is renovated by fire, make up the age of ages, which period is called the Kingdom of the Son of Man. However, when He "shall have put down all rule and all authority and power, for He must reign till He has put all enemies under His feet", then Christ as the Son of Man, shall surrender the Kingdom to God, that God may be all in all (1Cor.15:28). This is known as The Great Abdication.
There have been many abdications of thrones in the world's history, but none like this. Thrones have been abdicated for various reasons: some have been forced, others voluntary; some on account of physical infirmity, or to secure some particular successor. But Christ will not abdicate for any of these reasons; He will abdicate because He has finished the work that was given him to do as the Son of Man. He will not surrender his human nature, but His title Son of Man will merge back into that of Son of God so that the Divine Godhead shall thereafter act in its unity, and God shall be all in all.
As the creative ages were the alpha ages, these will be the omega ages. With the surrender of the perfect Kingdom to the Father, what we speak of as time ceases, and the eternal ages, called ages of the ages begin. They correspond to what the Apostle Paul in his letter to the Ephesians calls the ages to come (Eph.2: 7). And John in the Book of Revelation says that the devil and the beast and the false prophet shall be tormented day and night forever and ever, or for the aeons of the aeons, the ages of the ages (Rev.20: 10), and that the servants of God shall reign for the same period (22:5).
What those ages of ages shall reveal of the plan and purpose of God we do not know, but if we are His we shall live to know, and possibly take part in their development. What we do know is that we are but in the beginning of things, and as concerning the ages, eternity is still young.
The Servants of God
4 They shall see His face, and His name shall be on their foreheads.
5 There shall be no night there: They need no lamp nor light of the sun, for the Lord God gives them light. And they shall reign forever and ever.
