If Sunday's sermon grabbed your interest and you want more information, here are more articles that you may find interesting (yesterday's links can be found HERE). Most articles have two links. One takes you to a website; the other is for a pdf download:
"Updating the NIV: Notes from the Committee" – great article from the translators!!!
"What Happened to John 5:4? (Great and very short article explaining Textual Criticsm)
Use what's helpful; ignore what you'd like. I don't mind doing the legwork for you. So feel no obligation to read any of these articles.
