John 8, 37 “
I know that you are Abraham’s descendants, but you seek to kill Me, because My word has no place in you. 38 I speak what I have seen with My Father, and you do what you have [
n]seen with your father.”
All Jesus says is they are Abrahams's descendants according to the flesh, their genealogy is true, straight back to Abraham. But spiritually they are of the devil, meaning God is not their Father, they are not born of God, so they are not God's children, none of them are of God. They follow the devil, note Ephesians 2.
Those who are 'of God' hear God speak, and they love Christ as they are being 'of God' have been born again by the Spirit.
If you are not of God you won't hear God speak and you will hate Christ, even to seek to kill Christ as children of the devil hate Christ and seek to kill Christ.
This is a spiritual truth being exposed here.
42 Jesus said to them, “If God were your Father, you would love Me, for I proceeded forth and came from God; nor have I come of Myself, but He sent Me.
47 He who is of God hears God’s words; therefore you do not hear, because you are not of God.”
1 John 5
Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him.
John 10
10 He was in the world, and the world was made through Him, and the world did not know Him. 11 He came to His [
c]own, and His [
d]own did not receive Him. 12 But as many as received Him, to them He gave the [
e]right to become children of God, to those who believe in His name: 13
who were born, not of blood, nor of the will of the flesh, nor of the will of man, but
of God.
