Judaism says:

“Yahweh, He is God in heaven above and on the earth below; there is no other.” Deuteronomy 4:39

Christianity says:

Yes, of Gentiles too, since there is only one God, who will justify the circumcised by faith and the uncircumcised through that same faith” Romans 3:29-30

Islam says:

“In the name of God, the Merciful, the Compassionate.
Say (O Muhammad) He is God the One God, the Everlasting Refuge, who has not begotten, nor has been begotten, and equal to Him is not anyone.” Qu’ran Chapter 12

So,

Call Him by any name.

It doesn’t matter what a particular religion calls Him.

It doesn’t matter how a  particular religion worships Him

IT’S THE SAME GOD!!!! 

IT’S THE SAME GOD!!!!

Why,

In God’s name,

Are we killing each other over a name?
