ok, here is one that I have asked many JW's and they usually turn on me real quick. In the Bible teach book, it says that "true" worshipers teach others about God's name, his purposes, and his qualities. - pg 148. on page 147 it spells out the qualities of "true" worshipers.
ok, now here is my question, if this defines what a true worshiper is, were Abraham, Issac and Jacob "true" worshipers?
The answer is usually yes, of course they were. I then ask them to read Exodus 6:2. Here is Exodus it clearly states that God told Moses that He appeared to Abraham, Issac and Jacob as God Almighty, and God never told them His name. So the revelation of God's name was only from Moses onward. Since Abraham, Issac and Jacob never knew God's name, Tehy never spoke of God's name and made it known, were they "true" worshipers or not? According to the Bible teach book, they are not.
