I am not omniscient, but I could predict that my preschoolers would get into the cookies when they were left out.
How much more would an omniscient Creator be able to know what will happen before it does.
The Lord created time, stands outside time, and sees all things throughout time.
That is not “predestination”. That is just seeing what will happen, not making it take place.
Man always has free-will. God knows what we will do, but loves us enough to let us have our way, and hopefully the lessons we learn will not be lost.
I don't believe this is always true.
One example I gave already was the Pharoah's heart being hardened. Another example would be in our current era, The Age of Grace.
Rom. 8:29 For whom He foreknew, He also predestined to be conformed to the image of His son,... (30)Moreover who He predestined these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
A different example would be the Millennial Reign where I believe man is given free will and the result was rebellion.
