41 “You are doing the deeds of your father.” They said to Him, “We were not born of fornication; we have one Father, even God.” 42 Jesus said to them, “If God were your Father, you would love Me; for I proceeded forth and have come from God, for I have not even come on My own initiative, but He sent Me. 43 Why do you not understand what I am saying? It is because you cannot hear My word. 44 You are of you father the devil, and you want and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature; for he is a liar, and the father of lies.
- John 8:41-44 (NASB) Emphasis is mine.
Children possess the nature of their parents. Unsaved people possess the nature of their father, the devil. They do the things which are of Satan. This is their slavery to sin. But when a sinner comes to Christ and is saved, he or she becomes a child of God. That is their identity. They now begin to do those things which are of the nature of their Father, God, because God’s Spirit resides within and gives them a new nature.
