Brother, we do have the same God, just like we breath the same air.
We don’t all worship God or even recognize His existence. But He is our God. He is the primary fact of reality. Or I should say - He IS reality. To quote God Himself: ‘I AM’.

May Christ break their bitter and evil religion and bring them to Himself. Amen.
