If the name Jehovah is so important, then why is it never used in the entire Greek New Testament?

[Jesus.defender]

If the name Jehovah is so important, then why is it never used in the entire Greek New Testament? If men edited out the name of God, "YHWH" when they copied the New Testament, as only the Watchtower organization claims, then how can we have any confidence in any of the New Testament? Should we discard the New Testament or the Watchtower organization as unreliable?
 

[John Houston]

Who said it was not used in the NT? It is being said where the name is used when translated it was removed for 'lord' and  'Christ' in the Greek and when retranslated into English it was not back to YHWH. It stayed as Lord and Christ so the Father's name came to be confused. How can you quote from the Hebrew Scriptures word for word, using his name, then not translate it into Greek? But if you use another holy word for God, when it was translated into English, knowing it was quoted from Hebrew should it not then have been translated back to his name? The WTBTS correctly followed the flow of what should have occurred, not what everybody was doing. Not being superstitious and such. Common sense is powerful!
