Proceed with caution on this site, as it does ask for your contact info. (no doubt to spam you in the future). But this is a good start if you want to get started reading while waiting for a hard copy book to arrive from Amazon. The page numbers are not the same as the paper version...so when we have bible study, livestreams, etc, hopefully Apostle will mention the verse number, and we can search in the document by verse number, not by page.
Hope this blesses you.
