[Ali Imran]

How did God play with people's salvation, pray tell?

The God of Jesus didn't play games with people's salvation. It was a rhetorical question. I made that rhetoric because of what you believe. I'll explain.

For thousands of years, God has been telling people through God's messengers that God is one and there is no other besides Him. If you take others besides God as equal to God, you will be condemned to hell. And then suddenly, as per your belief, two others besides God are also gods, and if we don't believe that, hell will be our abode. That's what I mean when I made that rhetorical question. 

Also, God told people that God is not a man. And then suddenly, as per your belief, God became a man and if we don't believe that, we will go to hell, as per your belief. Is that God playing a joke on us? What would our father Abraham pbuh who is God's friend say if he knew God is actually 3 gods in one when throughout all his life, God has been telling him that God has not partners?
