Also if your church (assuming that it is a New Testament, Bible-based, Baptist church) has a book table, or a bookstore, or a smaller type of a bookstore (i.e., a book table) that would be a great place to find some worth while reading materials, no doubt. If you know of any good online Baptist bookstores for me to consider, please feel free to recommend them in the comments sections (heads up: any ones I disagree with won't be posted though, just saying). Be well.
