I can’t help but think you have been wrestling with this topic and grabbed a concordance, looking up every reference of the word hell in the Bible… and then supported your argument with those references. If that is the case, here are some other references that deal with the given semantic domain.

2Th. 1:9-10 They will be punished with everlasting destruction and shut out from the presence of the Lord and from the majesty of his power on the day he comes to be glorified in his holy people and to be marveled at among all those who have believed.

It seems as though the eternal nature of the said verses very much allude to the very thing you are arguing against. I would like to hear your thoughts. Have a wonderful day.
