One who says, "I know him," and doesn't keep his commandments, is a liar, and the truth isn't in him.

 Parakletos ( G3875) itself is a word which is passive in form and literally means someone who is called to one's side; but since it is always the reason for the calling in that is uppermost in the mind, the word, although passive in form, has an active sense, and comes to mean a helper, a supporter and. above all, a witness in someone's favour, an advocate in someone's defence. It too is a common word in ordinary secular Greek. Demosthenes (De Fals. Leg. 1) speaks of the importunities and the party spirit of advocates (parakletoi, G3875) serving the ends of private ambition instead of public good. Diogenes Laertius (4: 50) tells of a caustic saying of the philosopher Bion. A very talkative person sought his help in some matter. Bion said, "I will do what you want, if you will only send someone to me to plead your case (i.e., send a parakletos, G3875) , and stay away yourself." When Philo is telling the story of Joseph and his brethren, he says that, when Joseph forgave them for the wrong that they had done him, he said, "I offer you an amnesty for all that you did to me; you need no other parakletos ( G3875) " (Life of Joseph 40). Philo tells how the Jews of Alexandria were being oppressed by a certain governor and determined to take their case to the emperor. "We must find," they said, "a more powerful parakletos ( G3875) by whom the Emperor Gaius will be brought to a favourable disposition towards us" (Leg. in Flacc. 968 B).
