About other gods-question for theists

[orangebox21]

As a theist you believe in a god. But what about all the other gods? How can you say yours is the only true god when the fellow next to you has his own holy book or ways of worship?
How do you know there is not more than one, are maybe you are worshipping different faces of the same supernatural being who is having a laugh?
If your god is the true one, why does he allow other gods to be worshipped?

Offering a Biblical perspective.

The Biblical God says that He is the only God (Isaiah 44:6,45:5). This statement is either true or false. If this statement is true then there are no other God's. If this statement is false then either there is no God, many God's, or another one God but not the one in the Bible.

From a Biblical perspective, is it possible that there is one God with many faces? (I'm assuming your speaking of ecumenicalism-many paths to one God) No it is not possible. A simple answer is found when Jesus says, I am the way and the truth and the life, no one comes to the father except through me.

If you prefer a more intellectual approach consider a comparison between the Bible and another 'holy book'. If the Bible is true then there is only one God and this God cannot lie. If there is one God then all books claiming to be from God would be from the one God. If God cannot lie then there would be no propositional statements between the books that violate the law of non-contradiction.

For example let's look at the Bible and the mormon theology. From the Journal of Discourses, volume 1 page 121, "Remember that God our heavenly Father was once a child and mortal like we are, and rose step by step in the scale of progress, and in the school of advancement has moved forward and overcome until he has arrived at the point where he is now." From the Doctrine and Covenants states in section 130, verse 22: "God the Father has a body of flesh and bone as tangible as man's."

The Bible states: "Yet a time is coming and has now come when the true worshipers will worship the Father in spirit and truth, for they are the kind of worshipers the Father seeks. God is spirit.." And to qualify what a spirit is: "They were startled and frightened, thinking they saw a spirit. Look at my hands and my feet. It is I myself! Touch me and see; a spirit does not have flesh and bones, ..." So spirit equals not flesh and bones.

So we have two propositional statements that cannot both be true. "God the father has a body of flesh and bone" and "God the father does not have flesh and bones." The mormon church claims the Biblical God is true, then deny Him.

From a Biblical perspective your choices will always be between the Bible and something else. Therefore there isn't "one God many faces."
