Ok, so now we can move on. We've established that omnipotence does not mean the ability to choose from multiple realities. Correct?
No that is not correct. The truth has limitless realities which He can create, however His loving truth does not contain lies nor any loveless realities so lying realities He is not the author of, neither loveless ones. So this does put a different spin on your perspective of what omnipotence means. In God there is no darkness at all.
So next, does omniscience mean that god had foreknowledge of all things about this creation of his?
Sure God knows precisely what each deed entails and where it leads to so from that perspective He is all knowing. He can also see what lives in peoples hearts in real time so from that perspective He is also all knowing and finally we know from Jesus that God knows our hearts so well that He can predict what choices we will make in the future. So yes indeed God is all knowing.
He knew there would be a possibility that we would make the wrong choice. We have been given a free will after all. He also knew what this would entail - see His warning to humanity in paradise for example. However He also knew that in His love He would win His offspring back again and make everything well and be given the opportunity to excel His own loving truth which evil sin would stuff up so badly,. Yet He knew that ultimately His loving truth would be resurrected into an even more glorious majesty than He carried before and that hope gave Him the endurance to leave sin unpunished and suffer the free will of His wayward children.
So in His love He created humanity fully aware of the risks, for He wanted to share His goodness with as much life as possible and because He loved us enough to give untrue and sinful life form being in His loving truth even though we were not truthfully His offspring any more in their untruthful realities. and we would betrayl and murder Him countless times.
Such truly is the miracle of His love.That He knew whatever way we would choose He would be able to make something glorious out of it for all involved.
Does this mean that God conceived evil? For be it from true. He never willed it. Stickily forbade it. Rather He and all His own have always suffered it. He has always told us not to lie and not to be evil for He doesn't lie and He doesn't do evil and He wants us to have life in His loving truth and not existence in harmful lies which hurt, pervert and kill true life. Such bad life He for knew would cause Him and His own enormous suffering. This truth has been clearly demonstrated by His Son Jesus and His agonising death on the cross because of humanities loveless untrue choices.
God is more often the the victim of our choices rather than our choice that is what has gone wrong in His otherwise awesome creation. We choose to ignore His love and follow the lies all around cutting Him off from our existence and dying to His good life.
So no the God of Christianity is not the god you make Him out to be. Rather than being guilty of any crime He is proven to be completely innocent of our choices and unbelievable gracious that He would make something good come out of our wilful acts of rebellion. Lets praise His holy name and repent of all untrue and loveless lies dwelling with in us and submit to His loving truth.
Peace.
