Christians say God can do anything but can God if God wanted to stop existing disappear or stop being God could God make a stone/rock God could not lift we see God has a nature of God's own nature and won't do anything outside of God's nature God is eternal has always existed and always will exist therefor Christians are wrong to think God would become a human/animal one of God's creation also there can only be one God because God is in no need of partners other gods or a son would anyone agree with this I think God is perfect ?​
