I understand, but once you explain that concept - then you have to tell them the flaws in their understanding, and how your concept is much more true - stronger and easier to understand.
A powerful argument by the Prophets would be; whats better One Powerful Supreme God? Or lots of different gods who can neither see or hear and are themselves created? You should also ask them - who do you pray to if the other gods aren't in your presence? They'll say - the One God who is above the skies, then say to them - why don't you worship Him all the time, if He is the One who truely helps you at times of hardship? The One who is aware of all that you do and aware of when you call out to Him for help. He doesn't need intermediaries - since He is the All-Hearing, Seeing and prepared to respond to you if you call out to Him?
