I live in a community where we predominantly worship two gods. The mode of practice of worshiping these two are very different. We in the separate sects observe different rites in our worship practices. The striking thing is that we have unbiased beliefs about our God. For instance, the christians believe that Jesus Christ is the Son of God. On the contrary, the Moslems believe that God has never gotten a son. These are extremely two different things. The deception about the whole issue is that each believes that those who follow the other sect will end in fire. Who is deceiving who? How could we then soothe ourselves with the lie that we are serving the same God?
I agree with the view of Bro Eli Soriano in this video that we are not serving the same God. That we have different rites which are opposed to each other, it means that we do not have the same God. Our religious practices clearly show that we are serving different entities. God could not reject something from one person and then accept it from another. That god doesn't know what he is doing. Let it be clear to everyone that we are not all serving the same God.
The bottom line of this question is that where your God is, there we will be. If your God is the true God, then you will end with Him in his heavenly glory. If your god is the false god, you will be destroyed with him in the fire.
