If you grab a random person, even a random christian, and ask: "Hey! Does the Bible say our souls are eternal?" Most people assume that it does... but it doesn't! It says the exact opposite!
"...the soul who sins is the one who will die" Ezekiel 18:4
Some may now ask: "If the soul dies how can we live forever in heaven?" Well, it was actually a Greek philosophy that humans are made up of only 2 bits; the body and the soul. This theory gradually seeped its way into christianity as the early church evangelized to the gentiles. Using their existing ideas as analogies kinda got things a bit mingled!
The Bible actually says there is the Body, the Soul, and the Spirit. God breathed spirit into the body he had formed from the dust of the earth... When spirit met body, man became a living soul. It's a pneumatic + psychological + sematic structure. The body is how you perceive and observe the world, your soul is thoughts and emotions, and the spirit is the sort of, inner knowledge of right and wrong, and your connection to God.
Well, this post has no real conclusion, it's just a big tin of thought-food. So I'll wrap it up with a request. Can you think about it and maybe decide what you believe?
