This Pillar commentary seeks to clearly explain the meaning of John's letters to teachers, pastors, and general readers looking for a reliable resource for personal study. Colin Kruse introduces the important issues involved in interpreting the Johannine letters, gives verse-by-verse comments, and provides extensive discussion of John's major theological themes, including the real humanity of Christ, atonement, the role of the Spirit, Christian assurance, the meaning of koinonia, Christian love, and eternal life.
Tyndale New Testament Commentaries takes the book section-by- section, drawing out its main themes. It also comments on individual verses and faces up to problems of interpretation. Additional notes give a fuller discussion of particular difficulties. The aim throughout is to get at the true meaning of the text of the Bible and to make its message plain.
