well, as i see it - the bible mentions crowns saved up for us. now, if it were banjos - it would be specified. and yet, if we are made in the image of God and 'it does not yet appear what we shall be...' - but God calls us His children - then we will be LIKE HIM (not Him of course - but spiritual bodies that don't die). we will have creative abilities. the ability to create as many banjos as we want.
i think God enjoys the process of creation and He allows us to have a foretaste of it here. He also says that there are 'pleasures forever more...' with Him. they must be better than sex because He says we will be 'neither male nor female.' what kind of pleasures we really don't know and have to trust Him on this one. but, think - if He made sex in the first place and it was His idea and creation - surely He can make something even better and know that it IS better.
lastly, in revelations - He mentions a city (capital) of the entire world - who's streets are paved with precious stones. 'and he carried me away in the Spirit to a great and high mountain, and showed me the holy city, Jerusalem (the new one), coming down out of heaven from God. having the glory of God. Her brilliance was like a very costly stone, as a stone of crystal-clear jasper. It had a great and high wall with twelve gates, and at the gates twelve angels; and names...and the material of the wall was jasper; and the city was PURE GOLD, like clear glass (reflective and yet visible). the foundation stones of the city wall were adorned with every kind of precioius stone.'
it keeps on describing the city as better than any palace or hotel we have ever laid eyes on. i remember once seeing the hearst castle (although we didn't get to go inside because it was closed that day) - and thinking how fun it would be to enter. but, can you imagine God's own city that He has been preparing since the foundation of the world for us? He is busy creating as we speak - our eternal inheritance. if we look at the heavens - this is just a portion of what He has created. there is MORE. that we can't see right now. the spirit element.
really - i haven't a clue what being ressurrected and having a spiritual body is like. but, i do not believe that when we die that we will not be ressurrected and with God if we trust Him now. i think that everyone will have a chance to know God and choose between life and death. literally forever. to be with God forever or to be dead forever. hell, explained in revelations is the second death. to die, and not to be alive anymore. the beast, false prophet, and satan are said to be the ones to be in 'torment' - because they will be in a 'lake of fire' or darkness. spirit beings cannot burn up - but they will stay with all of the forces of destruction they used on this earth when they attempted to destroy it. just looking at the evil that they enjoyed using - and contemplating their bad move to be apart from God and choose evil instead of life and light. once a choice is made and the consequences given - it makes God a more real and powerful figure. He cannot live with evil - and chooses to isolate it.
