I am new here btw but here is a thought I had on this subject.
YHWH or some form of it appears to have been used in the OT. Whether or not it was used or how often it was used is irrelavent for this discussion. Apparently the use of it was stopped (supersticiously? or did the Jews have a reason?) before the time of Jesus / Greek / NT times. The Apostles, who IMHO had a more intimate relationship with God and Jesus than anyone after their time, did not use YHWH or Jehovah. The Greek word they used is Kupiou which translated is Lord. Even the Interlinear Translation agrees that Kupiou/Lord was used in the Greek scriptures. The "restoring" of the name of Jehovah to the Greek scriptures has no value. We put our faith in those scriptures that they are the perfect word of God written with the help of the Holy Spirit through the hand of a man. Yet they retain their perfection. To believe that the word of God is flawed would put the foundation of our faith in jeopardy!
Would you study a science book or math book if you KNEW that it had numerous severe mistakes?
The only way to claim that the original Greek scriptures are flawed AND that another translation is correct, is to say that one has "divine inspiration". Sound familiar? If that person or group does have that divine inspiration then misinterpreting the date of Armageddon would not be possible. Or is it?
