It is hard to say exactly what will happen during the everlasting life after the 1000 year kingdom.  But there are some clues in the scriptural descriptions of the Millennial Kingdom on Earth. Revelation 21:4. “God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.” This tells us the former things (the sin-sick dying conditions of the present) will be no more. Additionally, all the world will serve and love God and his righteous ways “forevermore” from Isaiah 9:7. Of the increase of his

[Christ’s] government there will be no end…. It will be established with justice and righteousness forevermore.”

So, at the end of the thousand-year Kingdom of Christ, as mankind stands at the threshold of eternity, they will look back upon this present life of suffering, sickness, sorrow and death. Though this experience seems dark and interminable at present, then, by contrast with eternity, it will seem trifling.  With this grand perspective, what this world is coming to now is seen as only a necessary bridge that passes over into life everlasting. Is it any wonder Jesus taught us to pray, “Your Kingdom come, your will be done on earth as it is in heaven”?

 As to the activities of the Church and other classes at the end of the 1000 year kingdom, we are also not explicitly told in the scriptures. Those who are of a heavenly class will continue to do their Father’s will.  We may conjecture or take a guess that perhaps since God does not create anything in vain, maybe the heavenly realm will focus on all the other planets and solar systems to develop them using Earth’s example with sin and its consequences. Isaiah 45:18  “For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited…”
