The bible says that the first man is of the earth earthy and the second man is the Lord from above. You might say that perhaps it meant the Lord Jesus, but what does Galatians 4:1 say? It says; Now I say, That the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all.
He is Lord but because he is a babe, the bible says he is a child and differs nothing from a servant. This is the difference between a man who is grown in God and one who is not; that is the pendulum; it swings between nepiosand teleios. Nepios is one who is untaught. That is the essence of the fivefold ministry. He gave some prophets, pastors, evangelists, apostles and teachers for the perfecting and growing of the saints into a perfect man[Ephesians 4:13].The word used therein for perfect man is teleios. The pastor, evangelist, apostle, prophet or teacher is perfecting, growing and maturing you unto a spiritually mature man.
Let us look at John 1:12-13 AMP. It says; But to as many as did receive and welcome Him, He gave the right [the authority, the privilege] to become children of God, that is, to those who believe in (adhere to, trust in, and rely on) His name— 13 who were born, not of blood [natural conception], nor of the will of the flesh [physical impulse], nor of the will of man [that of a natural father], but of God [that is, a divine and supernatural birth—they are born of God—spiritually transformed, renewed, sanctified].
The Greek word used in John 1:12 for children is teknon. The definition of teknon in its simplest sense is, a direct descendant by sperm; an offspring. Teknon means you are entirely the seed of God, so according to God, you are his child 100%. That is where Christians have a problem. I have only seen it in the Christian faith where children fear to share the father’s name. They are too humble.
Let us see another term in Romans 8:14. It says; For as many as are led by the Spirit of God, they are the sons of God.
The word used for sons here is huios. He says that for many as are led by the spirit, those are the ones who are huios. The translation there is that they are in a relationship. That means there is a place of becoming a child of God by reason of relationship.
