I would submit that, though the possibilities for choices each second are nearly infinite, there is but one future – and that is the future that will happen.
I could stand right now, I could remain seated. I could jump up, or I could turn around. I could do a hand-stand, or I could play in a band. I could soar a kite, or I take a bike. I could fly to the moon or I ride in a hot-air balloon.
~My version/mimicry of Dr. Seuss
If God is outside of time, is there only one future? Or is there many and God lives in each one?
So I hold the negative position. I hold that though there are many possible futures, there is but only one that will occur, and thus, the future can not be changed.
