2 John 1:7; 2 John 1:12

7 For many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh. This is the deceiver and the antichrist.
12 Though I have many things to write to you, I do not want to do so with paper and ink; but I hope to come to you and speak face to face, so that your joy may be made full.
