I believe as Christians that we have only one God in the entire universe so in him we live and move knowing that God is an incarnate that is personal.
We need to know God more personally for ourselves. The relationship we have with him defines us as Christians. It's not everybody that allows us to believe. Different kinds of people emerge from different backgrounds and have that different kind of worship.
According to what God teaches us, we are aware that God has made himself known to his own. Jesus came to earth and we are made to understand that God him. Through God is a relationship between us. Those serving the one God are the ones that usually turn around to be that true God in life.
We all must serve that living God.
