Did you actually think of that argument yourself or did you copy someone else?
That has got to be the most trolled argument for trolls.
Who really cares about what God's name is and who is using it. There are more important things to worry about.
If it were important, it would have been preserved. But if it is not important than the arguments that JWs have made could not have been made. It is possible that he left it unpreserved as a test for his people interested in the name to find and use.
Leave it as something that we will never know the truth about until God reveals it.
And as stated above, no one uses Jesus' given name, so why is it that everyone complains about the use of God's name?
Be consistant in your complaints.
