Romans 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
Who would want a God who couldn't know the future regardless of people's choices? Our God not only knows the future, He is already there. It makes sense to pray because God knows all things and God controls all things.
Our God knows the beginning from the end---His eternal purpose, and His plan for the ages will be accomplished.
When the world around us seems out of control, we can know that God is in control, that all things work together for good to them that love God, to them who are the called according to His purpose.
