1 John

John was the last apostle alive and wrote to combat the heresy teaching of a group called the Gnostics which spread false doctrine. He writes to set the record straight as he walked and talked with Jesus for years. Thus, he could refute false teaching with eyewitness accounts. John writes to combat heresy, teach about love, and provide assurance of salvation.
