Hmmm
While I agree with pretty much what everyone said...main point being the word of God is the only source of truth we need....I'm not sure I'm following here.
I went back and re-read the opening post, and this individual says this is something God placed on their heart to do. Of course I don't know all the particulars related to that, or how this book will go about addressing these things, but there are many many good books that pull scriptural principles into focus and help show people how to put them into practice. Not that they couldn't get the same from ONLY reading the word of God, but don't we all go every Sunday to hear a MAN preaching and teaching about these very things which help us understand various biblical principles?
Unless I am completely blind and didn't see something mcqueen stated that was questionable, I say, if God has placed it on your heart to write a book, and its going to be Biblical founded, then go for it! God has blessed me tremondously through His word, but ALSO various singers, preachers, ministers, and yes even authors too.
I just found the lack of encouragment a bit puzzling
but I've been slow before.....lol
Blessings!
