The Epistles of 2 and 3 John are written to believers living in a time when truth was already under attack. In the Apostle John’s day, deception had entered the assemblies. False teachers were pointing men to themselves rather than to Christ, and fellowship was being offered without regard for doctrine. John writes as a shepherd, calling God’s people to walk in truth and to guard the truth that had been delivered to them. These brief letters address the responsibility of believers to remain faithful to Christ, to exercise discernment in whom they receive and support, and to ensure that the next generation continues to walk in the truth of God’s Word. Truth is not merely to be believed, but lived, protected, and passed on. This book is designed to be used alongside a study guide, helping believers commit themselves to a settled walk in the truth revealed by God and to faithful obedience within the local church.
