Of course, one doesn't "finish" this book; it will be a reference for this season in Year B every 3 years! (Year B is part of the Revised Common Lectionary, a table of readings used by many mainline Protestant denominations and some Catholics, setting out readings for each Sunday of the year, one each from the Old Testament, Psalms, New Testament (letters or Acts) and Gospel.) Year A is mostly Matthew, B is mostly Mark, and C is mostly Luke. The Gospel of John appears throughout the other 3. This book is a commentary for preachers and others who want to delve more deeply into the Word. I recommend it.
