Where does wisdom grow?
Yes, together, engaging peacefully and lovingly, sharing our own opinions. Not quite “as we are now”, though. We will still be ourselves, but in a body that will never die, never get sick, never grow old. We will have enough differences to keep our minds sharp and be able to analyze and discern and examine and discuss and decide (along with so much more). It will be a life of pure joy. The only difference is that there’ll be no hate, no lies, no stupidity, no greed or selfish ambition, no immorality, no perversion. This is what the bible says.
But, what about people like hitler or trump or saddam hussein? Do they simply get to "get improved", or do they go "elsewhere"? (I already know your answer to that one.) So, what's the standard for determining who gets in and who doesn't? How good we think we are? If we've done a certain number of good deeds? No, the standard is holy perfection - and God said that none of us meets that standard (all have sinned). Therefore we’re ALL condemned to “go to hell” after we die. To be eternally separated from God, from every good thing, and from each other. No love, no hope, no light, no end. Yet because He loves us so much, He sent Jesus, His Son, to take our punishment for us. Through Jesus we can be declared "not guilty" before God (all our sins forgiven). It’s only through Jesus that we're able to reach God’s perfect standard. But all who refuse Jesus here will be condemned.
As Jesus was resurrected, we too will be resurrected (from the dead) – those who have “put on” Christ in this life, to eternal joy; all the rest to eternal damnation with satan and his followers. We may not like this (sounds too harsh), but we’re not the ones who set the standards. God has done EVERYTHING He possibly can to get us to be with Him for eternity. All we have to do is trust in Jesus (faith). If we refuse to turn to Jesus, we will die in our sins. We’ll never see our friends or loved ones, only eternal suffering.
God IS preparing us for eternity with Him. Problem is many don’t care. They’d rather live it up here and now, putting themselves ahead of God and hope everything will “turn out ok”; that maybe "somehow" they’ll make it to heaven, or that death will be the end of everything, or maybe they can come back and get a “second chance”. In Jesus, we can KNOW our future (100% guaranteed). Outside of Jesus there is no hope.
