You need to understand how time and eternity interact. Most people think time is linear - there’s eternity at one end, then a time line, then eternity at the other end. (Perhaps this looks familiar eternity)---time---(eternity ?) But that image is wrong. What we need to picture is a wheel. A wheel has a hub and a rim. Imagine God and eternity existing in the hub, and time running along the rim. With this image in mind we can see how, like randomly inserted spokes, God can reach out and touch any point in time, at any point in time.
Think about it. The day you are born, God enters the world to walk beside you until you die, and then He takes you home. Having spent your whole life with you, retreating only to bring you back into the hub with Him, from there God enters the world when your best friend is born, spends his entire life with him, until He brings him home. Then again, reaching into time the day King David was born, spend his entire life with him, until He brings him home. That’s how God is able to be with all of us, all of the time, at the same time.
Now, here in time we see that happening in a linear fashion... first the dead are taken, then at the very end a few remaining faithfull are caught up. But in the hub, we all arrive at the same time. 'Suddenly there was a multitude, rejoicing before the Throne of God'. That's us, our arrival into 'heaven'.
As for hell, God’s word tells us the world is made of things unseen, which describes the atom and it’s subatomic components. The interesting thing about the atom is that it’s nucleus is composed of like-charged particles, and orbiting that are like charged particles. The laws of science dictate that like charged particles repel each other, indicating the whole dang thing should just naturally come apart. But God says that all things are held together by Him (Hebrews 11:3; Col. 1:16). The Lord spoke this creation into existence, putting it together by His very Word (note the similarity of word/world). We are told that at the end of its existence the elements will melt with fervent heat (2 Peter 3:7, 10, 12). Consider what happens when an atom is split - it creates intense heat and fire as the element is ripped out of existence. Could it be possible that when God speaks it out of existence, the resulting nuclear meltdown of all created matter that now exists as our earth and heavens will create the lake of fire? Would it seem fitting that those who love this world more than Him would be given it, in its natural state apart from Him?
