The Gospel of John: A Theological Commentary. Eerdmans, 1997.
Ridderbos shines in so many critical areas for an engaging commentary of John. First of all, Ridderbos has a very robust theology of the supernatural character and nature of the Kingdom. Many of the elements of his timeless work "The Coming Of The Kingdom" are reflected in his handling of the signs and miracles. The glory of Christ has been revealed by Jesus, given to the church by the Spirit in this present age, and will be fully revealed and enjoyed for eternity at Christ's return. Ridderbos also pays insightful attention the person of Jesus and wittingly gives justice to John's own priority of bringing life to the characters and people that encountered the Christ. While the commentary has a very deep academic flair, Ridderbos delivers on often neglected feature of the Gospel, "The Word became flesh and dwelt among us." John's Gospel brings this to life and Ridderbos ensures that the reader doesn't fail to see this in John's account of Jesus. This is by far my favorite commentary of John.
