Some deep doctrine - most of it well reasoned and documented. I can't agree with everything Dr. Andrus says here but it still gives one much to think about. There is much about the pre-existence, cosmology and the creation we do not know but I am content to await further light and knowledge. It comes, albeit slowly and intermittently, sometimes when I least expect it. i understand much more now, at least to my personal satisfaction, than I did as a young college student over forty years ago when I was asking a lot of questions.
