Nice to hear from you again.
So what does a God look like - I (we) don't know. how much does it weigh? I (we) don't know. Don't know if God has weight even.God's Density, we don't know. volume, we don't know. So, do we know any of the physical properties of God? To be honest, NO, Nothing.
Now what about the mathematical properties-
To say that there is one God, you have to accept that there is a mathematical property in God , which enables one to Count God.
for example, one can count apples, oranges etc. But can we count space -NO, water -NO (these have uncountable property). we say little space, some water etc but not one water (one liter of water is different - it is the liter we count). In Hindu religion there is a saying, that "God is everywhere". in the water, in the air, in you , in me, etc. so if we take some water, there is God in it ( not some God in it)- Pour it into two glass and you haven't halved God as you pour it into the two glasses . there is not the same god in the two glass of water nor two Gods in those glasses of water, but God in those water. Is that the mathematical property of God - I don't know.
What I am asking is when we say one God, How do we know that God has this mathematical property which enables us to count God. what i am saying isn't it more truthful or more elegant to say just "God" than "one God"
I hope you get my point.
Personally, I believe we are all God sent. our morale, our subconscious inherent nature to do the rightful is the God sent message to each and one of us. And i definitely believe that God doesn't need the help of religion and Prophets to give us Gods message.
Thanking you.
