"Yet the number of the children of Israel shall be as the sand of the sea, which cannot be measured nor numbered; and it shall come to pass, that in the place where it was said unto them, Ye are not my people, there it shall be said unto them, Ye are the sons of the living God." (Hosea 1: 10)
Many Christians do not have the full revelation of their sonship in Christ.
They rest in the identity of fans or followers, yet never embrace the truth of their new family status with God.
"Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not." (1 John 3: 1)
Paul expressly preached this revelation to the pagan Athenians:
"For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring." (Acts 17: 28)
Why is this not preached?
Still don't believe it?
"For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father." (Romans 8: 15)
"6And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father. 7Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ." (Ephesians 4: 6-7)
It is very important for us to understand our sonship in Christ, which we receive through His Spirit living in us:
"Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God." (1 Corinthians 2: 12)
"But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him." (1 John 2: 27)
Do not settle for knowing that you are saved. Learn more about your sonship before God the Father because of Jesus:
"For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren." (Romans 8: 29)
"And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence." (Colossians 1: 18)
