Bible App by LifeChurch.tv
http://www.barnesandnoble.com/w/bible-lifechurchtv/1109941261?ean=2940043893352 This app needs Wi-Fi to function. You can get different Bible versions including KJV, NKJV, NIV, NLT, the Amplified Bible, and many more. It also reads the text to you on a couple of the versions. It is also very easy to navigate to find specific Bible passages. I have NOOK Tablet, and this app is awesome on the Tablet, but I cannot personally vouch for how it works on the NOOK Color. There are other free Bible apps, but this is the one I love the most.
