Isaiah 44:6 Thus saith the LORD the King of Israel, And his redeemer the LORD of hosts; I am the first, and I am the last; And beside me there is no God.
God continually claims to be the only God. The nations may have gods, idols, made with hands, but they are not God. God calls Himself the King of Israel. He is the redeemer. He is the Lord of hosts or the heavenly hosts, the army of angels and unseen beings.
I think as you read this it needs to establish firmly in your heart that there is only one God. So all the religions of the world are just that, religions. They do not have true gods. There is only one. Outside of the God of the Bible, there are no gods.
This is why the missionary life is required. We must carry the message of the God of the Bible to the world. He is the only one. What He says is true. All other religions are false.
