I purchased the Quest Study Bible 15 years ago and could not love it more. It contains so many notes and explanations. It has helped me gain a more thorough understanding of scripture and of how the OT & NT are related. This was my first study Bible and I am so happy I bought it.
I am now moving on to a different study Bible as this one is so full of notes I am going to give to my children one day. Sad to put this one up on the shelf, but it has served my spiritual growth extremely well.
This is my 3rd or 4th one ---each time I get one, a friend or friend of a friend say they'd really like one, so off they went (well,it IS one way to spread the Word, right!) So I figured NOW I can finally have one of my own since it was on sale again!! I always did like the NIV version--I love the questions being on the side--find it very informative too. I use it mainly as a companion Bible to my King James, which I must admit, will probably always be my favorite version altho I do have 3 other translations as well!
