不要依仗你的門派，你的門派不是所有人都接觸到我給你講的道理，他們不知就無罪，你卻是知曉的。

這是你和他們的本質區別。

20倘若他們因認識主救主耶穌基督，得以脫離世上的污穢，後來又在其中被纏住制伏，他們末後的景況，就比先前更不好了。
If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and overcome, they are worse off at the end than they were at the beginning.
21他們曉得義路，竟背棄了傳給他們的聖命，倒不如不曉得為妙。
It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them.
22俗語說得真不錯，狗所吐的，它轉過來又吃。豬洗淨了，又回到泥里去滾。這話在他們身上正合式。
Of them the proverbs are true: "A dog returns to its vomit," and, "A sow that is washed goes back to her wallowing in the mud."
