I don't think you even read my post, so in a nutshell: God's Word is one.
Oh my... I read your post, Didymos... the fact remains... You say "count the number of books in this picture", and then post a quote that begins with "no series of books"....
Yes, God's word is one... but the Bible, although inspired by God, was writen by various hands... so... you have many books!
If you want to understand that they are all one because they were all writen by God, it's your choice... but it's a falty logic... if so, Max Lucado only wrote one book... or CS Lewis... it's not because God wrote them all that it means it's only one book...
But, as I said... you stand by whatever you want...
