John 1:1, 11-13
1 In the beginning was the Word, and the Word was with God, and the Word was God.
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.
–Jesus has the power to make us the children of God. In the story of the Prodigal Son (Luke 15:11-32), the son reckoned that based on his actions and choices, he was no longer worthy to be called the father’s son; however, he was hopeful that if he asked very nicely, the father may take him back as a hired servant. Before the son was even able to get his planned speech out, the father immediately welcomed him back and among other things, gave him a family ring which in the culture of the day, was a token of one’s legal rights as a son and heir. What this prodigal’s father did for the son is the same thing that God does for us; it would be more than enough if He saved us from Hell and made us as servants for all eternity. But the Lord went much further than that; He made us “heirs of God, and joint-heirs with Christ.” (Romans 8:17) “Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God.” (1 John 3:1)
