There is a difference between opinion and doctrine. We get into trouble when opinion tries to pass as doctrine in a teaching setting. It’s okay to not know the answers and to the answer to a question be “I don’t know.”
But this I do know, the reason we are here – each of us – is to gain the highest possible outcome we can handle. Whatever that may be for each individual. The Lord wants me to have as much happiness as I am personally capable of. I trust in that statement so I don’t need to know the particulars at the moment of how that is going to work. Mainly because I probably couldn’t comprehend it anyway.
But I trust in the Lord.
