I have a question wrote:And here’s the other point about eternity, decision making is irrelevant. Because eternity. You literally don’t need to make any decision because there’s no time relationship. You just are, forever.
Eternity can mean of unending duration (of time), atemporal, or just some property that is infinite. Or just hyperbole pointing to one of those. While some will push for atemporality that's hard to reconcile with Mormonism and requires God be a kind of platonic entity of some sort.
While one can always debate the texts, typically God even in heaven is portrayed as acting, having feelings and doing things and thus being temporal. The main reason some lay Mormons get confused is because of the KJV of Rev 10:6 as "And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that there should be time no longer." This is generally just seen as a bad translation. The NIV puts it as "And he swore by him who lives for ever and ever, who created the heavens and all that is in them, the earth and all that is in it, and the sea and all that is in it, and said, "There will be no more delay!"
There are arguments against endless duration that go back to the medieval era of course. The Stoics thought the problem with infinite duration is that eventually you get repetition. (Thus the Eternal Return that later Niezsche made use of) However there's no real reason to assume the size of the set of time durations is the same cardinality as the set of possibilities.
