It is speculation about the mysteries of God. It is not doctrinal and plays no role in whether a person is saved or not. It is nothing more than trying to come up model of something the Bible is silent on.
I don't agree with Knight that time is part of God. I think time is something God created for us. And I don't agree that knowing what will happen in the future unchangeably settles that future. As I said, it is one of God's deeper mysteries for me.
The Bible is not silent and it is the glory of a king to search out a matter. Claiming mystery can become an excuse for lazy thinking or justification for believing inaccurate things. The debate is beyond your interest and expertise, but it is important, though not essential.
