Since God is Omniscient, knows ahead our choices and He also predestined prophesy, but also gives free will, the idea of election and vessels seems complicated.
God is Omniscient and Omnipresent
Its actually simple not complicated.
He knows my choices before I make them, but they are still choices made by free will, which we would make or have made regardless.
In other words if I make a choice of free will today, it’s my choice of free will. Whether or not God knew 1st, or didn’t know my choices 1st is irrelevant to my free will.
God pre-knowing my choices before my choices were made, doesn’t change the free will that God gave to us. Although it may change how God uses that choice.
God alters consequence for
1 - His own will and purpose and prophesy. “He works all things for good” 2 - He alters consequences at times for us because of His kindness toward us. But even those interjections of God in time where also foreknown by God.
Romans 8
“28 And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose. 29 For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brethren; 30 and these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified.”
He chose the exact time to come, at the right time, according to His will, to bring forth His prohesies, working all things together so God did it.
He predestined Judas’ betrayal. Not because God made Judas’ choice for him, but because he knew already that Judas would be offered 30 pieces of silver and he would choose and agree to betray Jesus. So God chose him to be predestined the Son of perdition.
So then God predestined Judas and his choices to occur in order to fulfill prophesy, occuring in the day and hour required according to His prophesy. Same with Pharoah. And other events like the killing of the babies when both Moses and Jesus were born. Weeping in Israel for her sons were no more" (paraphrased)
Prophesy is God’s response at the appropriate time and to every choice ever made and to every consequence that ever unfolded, past, present and future, and for His purpose to reveal the “anxiously awaited sons of God”
Romans 8
"anxious longing of the creation waits eagerly for the revealing of the sons of God. 20 For the creation was subjected to futility, not willingly, but because of Him who subjected it, in hope 21 that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. 22 For we know that the whole creation groans and suffers the pains of childbirth together until now. 23 And not only this, but also we ourselves, having the first fruits of the Spirit, even we ourselves groan within ourselves, waiting eagerly for our adoption as sons, the redemption of our body. "
Romans 8
26 In the same way the Spirit also helps our weakness; for we do not know how to pray as we should, but the Spirit Himself intercedes for us with groanings too deep for words; 27 and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to the will of God."
He already had complete foreknowledge of all choices and events ever to be made. Prophesy is His free will. He predestined prophesies at a designated time. And sometimes prophesies of God are simply just foreknowledge of events known from all the known choices and every action and reaction.
Prophesy is destiny.
Foreknown always! And predestined often! But in all thing according to His Will and purpose.
Our choices, and the consequences and the events that follow are simply used by God. We are jars of clay “should the created complained to the Creator, is He unjust?” (paraphrased)
God acts on His free will using our known choices and consequences. And He set in motion a purpose to have many like Jesus, the first born of many brethern"
God’s acts on our behalf, God knowing His actions beforehand doesn’t change God or His intervention, His purposes, His prophesies, nor their outcomes.
Whether happy or sad consequences, or objects of mercy or objects of wrath, or vessels of honor or for dishonor, He uses ALL for good, to fulfill His prophesies, and for His purposes throughout time.
His purposes could be as simple as feeding birds, confirming our faith, disciplining us to obedience, blessing us, and softening hearts or hardening hearts, to revealing to all of creation His children.
God knows all hearts and choices, preknown by an Omnicient God.
But knowing ahead of time doesn’t change free will, He doesnt change our choices because free will still makes choices our own.
