The entire premise of his argument is wrong. “Christians believe that there is one God and only one God”
God doesn’t even believe that. If fact, he said just the opposite. The only passages in the bible that is authored directly by God are the ten commandments.
“And the Lord said unto Moses, Come up to me into the mount, and be there: and I will give thee tables of stone, and a law, and commandments which I have written”
The first commandment is “Thou shalt have no other gods before me”
So, there are other Gods, and our God is insecure.
Now all the fundies will tell me what God really meant to say... Like God needs their help to get a point across.
Really? Either one of two things, you forgot your sarcasm tag which is sad because you are mocking God or you really beleive God Almighty is insecure, and if that be the case He is not worthy to be called God.
Any reasoned person would know what the meaning here, for instance I would say you have another god before you, and their name is “idiocy”.
You have completely distorted the meaning of that passage. God didn’t admit other gods exist. He merely prohibited one from believing there is another deity.
Also, there are other other Bible verses that directly quote God and reject your contention that are other gods. You don’t have a solid grasp of the Bible if you claim the ten commandments are the only passages directly authored by God.
