Did not Christ say many are called but few are chosen? There can be only one explanation as to why two times it was Written that God hated Esau and Jacob He loved. Their souls/spirits existed before they were placed in flesh body at conception.
Some are given ‘free will’, Paul most certainly was not given ‘free will’. Saul was doing his free will and he sure did not ask for Heavenly direction on his trip to Damascus. Yet he was interrupted in doing his free will and wrote extensively regarding those predestined from before ‘the foundation’ (means the overthrow - casting down) of the world (or as Peter calls it the world/age that was, IIPeter 3)
“Their souls/spirits existed before they were placed in flesh body at conception.”
I would be careful with this kind of conclusion, dear Brother, as it is essentially the Mormon position. It is not necessary to suppose that Jacob and Esau existed as spirits before they were placed on Earth just because the election of God took place before they had done “good or evil.” To take your position, it would suggest that Jacob must have done something right in the pre-existence, which warranted God having chosen him. But the scripture teaches that it is not based on our merits at all, and therefore this cannot be the case:
2Ti_1:9 Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,
We are also, by nature, designed to be alive as a union between a physical body and a soul. To be separate from the body originally, before being placed into the body, would say that our natural condition is to be what we call death. Yet, as we see in Revelation, our ultimate fate is to be a part of the 1st resurrection, regaining our physical bodies, though in a glorified state incapable of sinning, in the same way we are incapable to stop sinning right now.
