1, 2, 3 John - CCS by Curtis Vaughan and published by Classics.
Curtis Vaughan’s Commentary on the Epistles of John brings together in brief scope a distillation of his breadth and depth of scholarship as one of the great masters of the Greek New Testament. When you read Vaughan’s comments in digest form there is a sense that you have encountered scholarship set on fire by an intimate relationship with Jesus Christ, the Subject of all the Scriptures.
This Commentary on John’s Epistles is an excellent tool for biblically based self-examination and a basis for biblically grounded assurance.
