The Fourfold Gospel by J. W. McGarvey
This is a classic Harmony of the Gospels. I would recommend making it a goal to read through the New Testament this year and to read through this work after you have read all four Gospel accounts. I believe it will help you put all the pieces of the puzzle together for a clearer, deeper understanding. Some markings to the text as I have used copies of this work.
Solid bindings with markings to the texts.
