If Christ died on the cross for all of humanity

Those are a very very good questions and it's good to be curious!! I don't recall anyone asking that question before on this thread but it has to be a question that is commonly asked by many.

There are many passages in the bible that discuss heaven but of course it is not possible to understand the full nature of heaven from a human perspective.

The bible tells us, "He will wipe every tear from their eyes, and there will be no more death or sorrow or crying or pain. All these things are gone forever" (Revelation 21:4).

Believers will receive a new body. "It is the same way with the resurrection of the dead. Our earthly bodies are planted in the ground when we die, but they will be raised to live forever. Our bodies are buried in brokenness, but they will be raised in glory. They are buried in weakness, but they will be raised in strength. They are buried as natural bodies, but they will be raised as spiritual bodies. For just as there are natural bodies, there are spiritual bodies" (1 Cor. 42:44).

There will be no Sun or moon. "And the city has no need of sun or moon, for the glory of God illuminates the city, and the Lamb is its light" (Rev. 21:23).

Gravity will be absent or greatly reduced. Revelation describes the New Jerusalem as a cube 1,500 miles on each side. Under the current laws of gravity, any structure that size would immediately become a sphere. Therefore gravity would be either absent or greatly reduced. "And I saw the holy city, the new Jerusalem, coming down from God out of heaven like a bride beautifully dressed for her husband...And the city is laid out as a square, and its length is as great as the width; and he measured the city with the rod, fifteen hundred miles; its length and width and height are equal" (Rev. 21:2, 16).

There will be no sea. "Look! I am creating new heavens and a new earth, and no one will even think about the old ones anymore" (Isaiah 65:17). "But we are looking forward to the new heavens and new earth he has promised, a world filled with God's righteousness" (2 Peter 3:13). "Then I saw a new heaven and a new earth, for the old heaven and the old earth had disappeared. And the sea was also gone" (Rev. 21:1).

I doubt that heaven will be segrated because we will all be spiritually equal and you will not remember anything of what your body was when you were on earth. (read Isaiah 65:17)

Besides receiving a new body, those who enter heaven will be given a new name. "Anyone with ears to hear must listen to the Spirit and understand what he is saying to the churches. To everyone who is victorious I will give some of the manna that has been hidden awaqy in heaven. And I will give to each one a white stone, and on the stone will be engraved a new name that on one understands except the one who receives it" (Rev. 2:17).

We will be incapable of committing sin. "For the husbands, this means love your wives, just as Christ loved the church. He gave up his life for her to make her holy and clean, washed by the cleansing of God's word. He did this to present her to himself as a glorious church without a spot or wrinkle or an other blemish. Instead, she will be holy and without fault" (Ephesians 5:25-27). "But we are looking forward to the new heavens and new earth he has promised, a world filled with God's righteousness" (2 Peter 3:13). "On that day you will no longer need to be ashamed, for you will no longer be rebels against me. I will remove all proud and arrogant people from among you. There will be no more haughtiness on my holy mountain" (Zep. 3:11).

Therefore, we will not have all the problems we had on earth, they will be all gone. We will be able to enjoy each other's company without the fear of being hurt by anyone. It will be great to be physically and morally perfect and to have fellowship with others who have also been transformed.

There is so much more to say about what heaven will be like but that would mean I would have to type forever about it and so I just gave you a little glimpse of it. Perhaps I will just continue on it later on. For now just know that it will be paradise!!
