Ask a Witness this question and wait for the answer...... In most cases they will tell you they will return with an answer.

Open Question
Jehovah's Witnesses: What covenant are you under?
There was the Old Testament, where the book of the Law was by Moses and dedicated by the sprinkling of blood. (Hebrews 9:18:21) And the New Testament by the blood of Christ under the New Covenant. (Hebrews 10:15-22)
But isn't that new covenant only for the "anointed / spirit-filled / born-again" Christians that is limited to 144,000? (Who was the surveyor that kept track of this number through the ages?) I thought the Bible said "whosoever will, may come; and there's no respect of person with him?"
Anyway...if the above covenant is for a number of people that you are outside of...Which or what covenant (testament) are you under?
Where can I find that in scripture?
