There is only one God, and people who live the Jewish, Christian, and Islamic faiths all agree we are united in the belief we worship the very same God, who is One.
It is comical that someone who does not know God, holds no belief in this one God, does not worship God, and has only very shallow knowledge of religion presents himself as the expert on God whom we know and love. Comical and worth a chuckle, maybe two.
A wife can describe her husband, a child its father--the same man-- and you likely to insist they are "really" two different men. You "know" this because the descriptions are different. Throw in the younger child's teen brother and you would be convinced there are three different men! Three chuckles. (Still one man.)
