God can look into the future whenever he wants to.
So, whether he chooses to look into the future or not, the "future" is the "future", right?
I.e., he couldn't "look into the future" and see something that wasn't going to happen, right?
Anytime he chooses to use his "look into the future" superpower, that's what must come about, right?
If so, then the future is fixed, unchangeable. Jehovah is powerless to change it. If he changed it, then what he saw when he used his "look into the future" superpower would be wrong.
So either your Jehovah is not omniscient, or he is not omnipotent. It is literally impossible to be both.
Are you even sure you know what you believe? You sound really confused.
