What is the mode of salvation for the unborn dead, the insane, and the parasitic twin?
Problem with any unchanging entity that does not have a time scale to separate its actions is that it has to do everything it will do, at the same moment. This is impossible, and hence nothing can be changeless and timeless.
There is no moment, but I gave an analog. Something does not have to change in order to have different effects at different times on different people. It's not a deterministic view either.
I was talking about how God might be known. I don't believe it is necessarily a cognitive function. I don't believe you can "figure out God." I believe it is both simpler and more subtle than that.
Salvation is a whole 'nuther kettle of fish that I may have conflated with knowing. I'd need to understand what you mean by salvation to attempt even a lame response.
