I think it safer to return to where I was before I was born than to agree to an unalterable eternal contract.
unfortunately, you can’t go back to where you were before you were born. Your here now and there is only one of two places that you will go when your time here is done.
Check out the book by Randy Alcorn titled “Heaven” I think it may answer some of your questions. I have read it through once and I am reading it again. Good book on the subject of heaven and it takes all of its information from the bible.
