Can prayer change God's perfect plan?

[Fake Messiah]

Well, they claim that he is omnipresent which includes being present both inside AND outside time and space.

But the part of him that exists inside is the only part that can interact in the actual world and the only part that has any actual existence or reality lol.

So what you are saying is that god is an invalid because only part of him is in "our dimension"? He can only use his left hand which is in "our dimension" while the rest of him is in other?
Needles to say for anyone having the least familiarity with religion, it goes without saying that such watered-down versions of faith are not held by most people, who accept instead a personal god who intervenes in the world. It's simple ignorance. Rather similar like some Christians here on forum claim that all Christians acknowledge evolution. They totally ignore even other Christians on this forum.

Saying God is also outside of time and space as well as inside it.... is rather like me saying that the side meal I'm having with my main course is nothing.... and someone replies "Oh so you mean you have no side meal with your main course?" and the response I give is "No, I do have a side meal it's just nothing." Lol.

Yeah, perhaps but to me it is very like Carl Sagan claiming to have a dragon in his garage.
And also god of the gaps. Just moving god where we can't reach him yet. He used to be on high mountains, then sky, then another dimensions.
