If I've understood your point correctly (and I might not have), when someone becomes born again with/by the Holy Spirit, they are not immediately imbued will all spiritual wisdom. It is a continual process, but one that is directed by God who leads them into greater and greater (correct) spiritual knowledge and wisdom, which knowledge and wisdom conforms to, agrees with, and is subjective to, the Gospel of Christ.
The Holy Spirit leads into recognizing true and correct spiritual doctrine in order to serve as a basis for their "choices". Nevertheless, spiritual choices are not what saves someone (if that's what you're alluding to) -- only God can save.
As I'm not exactly sure how you're using the word "choices" I may have misunderstood your point. If so, please let me know - thanks
[Phl 2:13 KJV] 13 For it is God which worketh in you both to will and to do of [his] good pleasure.
Don't make it overly difficult, Brother. If someone was predestined as in, they have no choice, that is erroneous. Our life here on earth is all about free will. God does not violate free will and will never force Himself upon anyone. Ye have not because ye ask not...
1 Peter 1:13-15
13 Therefore gird up the loins of your mind, be sober, and rest
your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ; 14 as obedient children, not conforming yourselves to the former lusts,
as in your ignorance; 15 but as He who called you
is holy, you also be holy in all
your conduct, 16 because it is written, “Be holy, for I am holy.”.../
So clearly the idea is to press in and grow. That, the Lord will reward of you. The Lord will also reward you for not sinning and obeying Him in all He has said.
When we are saved and born again, the outward man does not change. We receive a new spirit within us which we can not see. And scripture says that
John 1:11-13
11 He came unto his own, and his own received him not.
12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.../
Some received Him not. (Lukewarm Christians)
The ones who did receive Him He will make into sons of God. But it's clearly by our perseverance and cooperation with Him. It sounds like a promotion... The way you talk Brother, you almost make it sound like once you're born again, it's finished, but the opposite is true for it has just begun.
The way I understand it, there are four levels of relationship with God. Servant, Friend, Sons, Brides. The first three we decide to press in for and the 4th one, the Bride...Jesus decides that one. So it sounds like there is plenty of room for improvement and promotions within the Kingdom of God. It all depends upon our will, our choices.
I think I remember a scripture which talks about how Angels go around measuring the servants spirituality height. That must be for promotional considerations? So our life is always under review. He has set before us life and death, therefor choose life.
