I say this because many deceivers are gone forth into the world, those who deny the coming of Jesus Christ in the flesh. This is the deceiver and the Antichrist.

Pay close attention to yourselves, so that you do not lose what we [Note: Some Greek manuscripts say "you"] worked for [i.e., the spiritual blessings you have acquired], but [continue faithful] so that you will receive a full reward. [See Luke 12:47-48; James 3:1; Matt. 20:1-15].

if any one doth come unto you, and this teaching doth not bear, receive him not into the house, and say not to him, 'Hail!'

for the one who says, “Welcome,” to him shares in his evil works.

Having much to say to you, it is not my purpose to put it all down with paper and ink: but I am hoping to come to you, and to have talk with you face to face, so that your joy may be full.
