Please read Exodus 3:5-14 to see what statement occasioned, for certain, the divine title YAHWEH (not Jehovah, by the way), misconstrued by many as the name of the Lord God. It is not so, however, because God can never be named. Among the ancient Semites, one who knew a name supposedly had power over the being so titled. Hence to know God’s name - as Moses requested - was tantamount to seeking power over God. The answer that God gave to Moses constitutes a refusal on God’s part to betray His name to man, consequently reaffirming His transcendent otherness.[cf. New American Bible Exodus 3:14]
Another way of putting it could be that God’s answer to Moses’ question about His name may be interpreted as “It is none of your business to know My name, much less to call Me by name because neither you nor any other human being has power over Me!!!”
Why, on the first place, they insist on calling God by name? Do they pretend to have any power over God? Why do they appear to push us to call God by name? Are they playing the tempter in pushing us to commit sin?
