If you are a Christian, then you have no choice but to accept predestination as a fact.

When God created all things He rested from his work.

It's done.

God did not created the universe and then it developed on its own.

Time is integral to the fabric of the universe. In the moment of creation God created all time and space that would ever be.

He created the end along with the beginning and everything in between. The complete package. Not just the beginning. Then he rested from his work. The end of time was set from the beginning.
