Now I say, as long as the heir is a child(nepios- infant, immature person), he does not differ at all from a slave although he is owner of everything, but he is under guardians and managers until the date set by the father.
For though by this time you ought to be teachers, you have need again for someone to teach you the elementary principles of the oracles of God, and you have come to need milk and not solid food. For everyone who partakes only of milk is not accustomed to the word of righteousness, for he is an infant. But solid food is for the mature, who because of practice have their senses trained to discern good and evil.
Yet we do speak wisdom among those who are mature; a wisdom, however, not of this age nor of the rulers of this age, who are passing away; but we speak God's wisdom in a mystery, the hidden wisdom which God predestined before the ages to our glory; the wisdom which none of the rulers of this age has understood; for if they had understood it they would not have crucified the Lord of glory; but just as it is written, "THINGS WHICH EYE HAS NOT SEEN AND EAR HAS NOT HEARD, AND which HAVE NOT ENTERED THE HEART OF MAN, ALL THAT GOD HAS PREPARED FOR THOSE WHO LOVE HIM." For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God.
And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able. For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
The Spirit itself beareth witness with our spirit, that we are the children(teknon-from teko, bear in travail) of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
And whosoever doth not bear his cross, and come after me, cannot be my disciple.
Everyone will be reconciled to God, but not everyone is reconciled to God now. Not everyone who believes in God and/or the Bible is reconciled to God. The Pharisees believed in God and the Scriptures but they murdered Christ. Of those who are reconciled to God now, some are building wood, hay and stubble and will be saved, but as through flames- losing their reward. The reward I am speaking of is the sonship inheritance, for overcomers only, and only God knows who they are. Everyone who is reconciled to God now is a child of God but many of the children are no different than slaves because they are immature and are not trusted by the Father with the keys to the kingdom- no more than I would hand my car keys to my grandson who is 5. He might kill someone or hurt himself. No one who opposes the gospel is a son of God- they are sons of disobedience. Those who do not oppose the gospel but are immature, stuck in the natural man, babes- are unable to walk in the adoption they are called to. Many are called, few are chosen. When someone is chosen, it is evident, because they have demonstrated maturity so the Father gives them the keys. The ultimate evidence of the sonship of God will be the redemption of our bodies spoken of in Romans 8.
That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death; If by any means I might attain unto the resurrection of the dead. Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus. Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before, I press toward the mark for the prize of the high calling of God in Christ Jesus. Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
Too bad no one ever taught Paul the four spiritual laws, he wouldn' t have had to worry about all this other stuff- and neither would we ;o)
