The “Why” questions in Christian theology, especially those pertaining to time, are mostly unanswerable. This presents a problem for the western mind, because we are trained to expect answers to all questions. But on these questions, we should adopt an attitude of unknowability. Some things are not meant to be known. A concept alien to westerners.
If it’s all a mystery and unknowable, it’s probably bs and should be ignored.
An omnipresent being should be able to communicate more efficiently.
