God is not going to accept anyone who is not obedient to His will, commands and statures. Other words if you are walking according to the flesh and the rudiments of this world then you are none of His.If I understand you correctly, you saying God chooses who are His based upon whether or not they are "in His will and obedient to Him" and chooses who to reject based upon their disobedience to His will?
If I am understanding you correctly, then I have a question: does God have the choice of rejecting a person "in His will and obedient to Him" or choosing a person that is not "in His will and obedient to Him?"
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
Rom 8:4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
Rom 8:5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
Rom 8:6 For to be carnally minded is death; but to be spiritually minded is life and peace.
Rom 8:7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
Rom 8:8 So then they that are in the flesh cannot please God.
