There's stuff in the book that is not understood properly, because it's translated and interpreted according to a poor understanding of Hebrew and Jewish culture and history. Actually, later on it's translated according to Greek/Roman culture, Christian religions and translating traditions. One of the central concepts in the Bible is chai le olam. It ends up something like zoea aionios in Greek. It gets translated as eternal life but doesn't really mean that. I would say it's more implying continuous life as opposed to fleeting, temporary life (chai le sha'ah). It's not so much about being immortal as it's about living a life that God will allow to continue rather than one he will put a stop to. I tried to understand the Bible once with everything being about the present life, but some things couldn't make sense. Then I concluded it's more of an integrated present life leading into the afterlife sort of thing. It's not all about the afterlife and collecting your ticket to heaven while sitting around waiting to die. As previously mentioned, Bible translation is often done according to religions and translating traditions. The KJV mentions something about receiving mansions in the gospel of John. The Greek isn't talking about houses or mansions at all but rooms. In the Father's house there are many rooms. This mansion nonsense was carried over into the NKJV translation even though it should've been blatantly obvious it doesn't say that. Usage of the word hell in Bibles is mostly just a disaster that totally misleads people. People generally don't have a concept of prejudgement and post judgement afterlife places when that is clearly depicted in the Bible. 1 Cor. 15 talks about natural bodies as opposed to spiritual bodies. This makes people think we're going to end up with ghost bodies. The actual Greek says we're going from soul bodies to spirit bodies. Souls (mind/will/emotions) are actually less tangible than spirits (ghost bodies). It's actually saying that currently the soul is in charge and the new body will have the spirit in charge. Currently, you're supposed to use your soul to turn to the spirit as opposed to the flesh. It's simply trying to say things will automatically be set to spirit in the new bodies.
