One of my favorite Bibles I've ever had is this thick Life Application study Bible. I studied that Bible every day for a few years. So when I saw the NKJV study Bible I knew I wanted to get it.
This Bible is a really wonderful study Bible. It has cross references on every page. It has study notes as well as little articles around the text. Keeping in mind that these notes are not God's holy Word they merely help us study iit. It also has maps at the back to see locations and things like that. It has a beautiful imitation leather and is very well made. It's pretty light so it's also great for taking with you.
All in all this would be a great gift for yourself or someone you know.
