 He calls Jesus Christ our Advocate with the Father. The word is parakletos ( G3875) which in the Fourth Gospel the King James Version translates Comforter. It is so great a word and has behind it so great a thought that we must examine it in detail. Parakletos ( G3875) comes from the verb parakalein ( G3870) .

It is, for instance, used with that meaning in Genesis 37:35, where it is said that all Jacob's sons and daughters rose up to comfort him at the loss of Joseph; in Isaiah 61:2, where it is said that the function of the prophet is to comfort all that mourn; and in Matthew 5:4, where it is said that those who mourn will be comforted.
