I say this because many impostors have left us to go into the world--men who do not acknowledge Jesus as Christ come in our human nature. It is that which marks a man as an impostor and an anti-Christ.

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.

I have a great deal to say to you all, but will not write it with paper and ink. Yet I hope to come to see you and speak face to face, so that your happiness may be complete.
