On all questions regarding regeneration, the basic question is: who’s your daddy? Outside the covenant, the devil is father. For the elect, God is our Father. But for the reprobate covenant member, God is his Father in a real covenantal sense, but in another tangible way, the devil is still his father. This is fully consistent with how Jesus addresses unbelieving covenant members. The emphasis is mine.
I know that ye are Abraham’s seed; but ye seek to kill me, because my word hath no place in you. I speak that which I have seen with my Father: and ye do that which ye have seen with your father. They answered and said unto him, Abraham is our father. Jesus saith unto them, If ye were Abraham’s children, ye would do the works of Abraham. But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham (John 8:37-40).
Ye are of your father the devil, and the lusts of your father ye will do (John 8:44).
Ye serpents, ye generation of vipers, how can ye escape the damnation of hell? (Matt. 23:33).
In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother (1 John 3:10).
