Another comforter

John 14:15 If ye love me, keep my commandments.

16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;

Jesus is using a term not strange for the jews in this verse. Comforter is the translation of the greek word parakletos. Parakletos was a legal term for something like a defending advocate. The latin version is advocatus, where we have our advocate from. 

The jews said that their good works was their parakletos in front of the Father. The only problem with that is that there is another advocate that screems louder. The accuser of the brethren, Satan. He is the prosecuting attorney. His case was always strongest. Thats why the Bible makes it clear that NO one was made righteous by their works. 

So here Jesus shares the good news with the jews. He will give you ANOTHER parakletos. Another advocate. 1 John 2:1 tells us that if we sin, we have a parakletos in from tot the Father. Jesus, our ADVOCATE.
