This question has been on my mine for some time now. Well if the Bible does not teach us anything at all it teaches us that we would be judged according to our works, then I guess some will be very obedient than some, others good, some better, some best. If thats the case our joy will depend on our dids, good or evil. If there is only one heaven then i guess paul was wrong to say the things he said when he discribed the three heavens he saw in the vision. Then I guess Christ would not have said ” In my fathers kingdom (ie. Heaven) there are many mansions”. Christ said what he said because he knew some of us will be more rightous in our dids towards the father than others, thus the parable of the talents… What do you think about HEAVEN? The bible teaches ONE BIG HEAVEN with Three divisions to serve our levels of obedience.
