'known,' 'predestined/predetermined' are basically the same when it comes to God. You may not know it but 'He' already knows every single move or decision(and the outcome) you will ever have to make in your life, so how is it free will? The outcome is already 'known' by God.
It is just one of the many God paradoxes.
Yes or No... If God is almighty, can he create a god that is more powerful than him?
Omnipotence paradoxes like the above have been around for ages. Can the people of any nation be self-governed? If so, can they appoint a dictator to govern them, whom they cannot govern?
Our imperfect and limited human languages cannot meaningfully address the concept of omnipotence itself.
Biblical omnipotence does not mean that there is nothing God cannot do. It means that God will never fail at what He sets Himself to do.
Even the Bible says there are things that God cannot do:
2 Timothy 2:13if we are faithless, he will remain faithful, for
he cannot disown himself.
Romans 6:9For we know that since Christ was raised from the dead,
he cannot die again; death no longer has mastery over him.
Galatians 6:7Do not be deceived:
God cannot be mocked. A man reaps what he sows.
James 1:13When tempted, no one should say, "God is tempting me." For
God cannot be tempted by evil, nor does he tempt anyone;
Titus 1:2a faith and knowledge resting on the hope of eternal life, which
God, who does not lie, promised before the beginning of time
