[Hope]

Hello Hope...glad that you are back. 
I thought you left your companion Alizabird for dead...
He has been putting on a brave front for a lost cause lah...now he needs your help to turn the boat around lah...

Yahweh is formless..but he appeared as a man in the OT and also as a burning bush when He spoke to Moses

What is a lost cause? You have no evidence to prove people who believed in your faith are already in heaven.As per Islam, all the dead  regardless of their religion are waiting at Barzakh.If you can’t provide any proof, How can you prove your faith is true?
If Yahweh has no features, How does he see, hear, help you?

Allah has features doesn’t mean he is a human.
Allah is not that weak to take a form of a human, Angel, Jinn and any other creatures.
