I am not a fan of this theory because I don’t like to think I’m little more than some animated character going through the motions that are already scripted for me. Not a fan of anything that says we humans have no free will. I don’t think that’s God’s plan for us, it would make us little more than puppets on strings.
When the Bible speaks of the "chosen" ones, we are not pre-chosen by him the day he creates us. But because He knows all truth past present and future, he knows what we will choose.. by free will.. in the future. And therefore He also knows which souls will choose well and please him and who, in the future, He is goning to choose to be allowed into eternal peace in heaven. He already knows who the chosen ones will be.
The athiest explanation of the guts of the theory are wrong, but the theory touches on some truth.
