I was taught in heaven, everyone equal.
Hardly the circumstance, far from being a communist society, heaven is a Monarchy. As the scriptures point out, even in heaven the duty of the Christian is to be subservient to our Lord God. The scriptures declare that Heaven is a spiritual realm, a place where God exists as a Spirit, thus we will not have physical bodies but spiritual bodies and become like the angels. Even in heaven there are responsibilities as the duty of each is to serve the Lord God.
Heaven will be populated by the Holy Godhead, the Father, the Son and the Holy Ghost (Rev. 4:8), by holy angels (Luke 9:26) and the just, those who have been made perfect by the sacrificial blood of Christ and the Grace of God (Heb. 12:23) those made just by the church of the firstborn (Christ Jesus).
There will be no possibility of evil existing in heaven as all those renegades from God's righteousness will have been sentenced to hell (Matt. 25:41-46, 2 Thess. 1:7-9, Rev. 14:9-12, 21:8, 22:15)
There will be an atmosphere of extreme joy.........but heaven is still a place of responsibilities. "Gods servants shall serve Him......" -- Rev. 7:15 And they shall find joy in doing so.
There will be no need of money or marriage in heaven, as spiritual bodies are eternal and do not require reproduction to replenish, as pointed out by Christ (Matthew. 22:29-30).
Will there be memories in heaven? Only happy memories as the scriptures declare, "....God Himself will be among those in heaven and wipe away every tear........" -- Rev. 21:3-5
Will we know our loved ones? Of course the loved one's who are actually in heaven as stated in (Genesis 25:8) where we are told, at death, Abraham was gathered to his people.
When David's child died he realized that the child would never come back to him, but he could go to where his son would be. (2 Sam. 12:23)
There is a passage in (1 Thess. 4:13,14) that gives hope to those who have lost loved one's to death, that they could one day be reunited with them.
Again..........our bodies will be changed from corruptible flesh to incorruptible spirits, ".....in the twinkling of an eye......" 1 Cor. 15:52
But heaven will be nothing like a communist commune..........all will still bow and serve the Lord God, the Holy Monarch of Heaven, because after the Christ finally defeats death at the final judgment, the kingdom is turned back to the Father (1 Cor. 15:24
