I just finished Opening John's Gospel and Epistles by Comfort & Hawley published by Tyndale. It is an excellent resource for anyone who is wanting to study the word on a deeper level. It is organized and clear and focused. The commentaries are wonderful and I loved how they broke down each verse, piece by piece. I would recommend this to anyone who is looking to dig deeper and in need of a study aide.
*Disclosure: Tyndale House publishers provided me with a complimentary copy of this book. I was not required to write a positive review.*
