John 8:31
So Jesus was saying to those Jews who had believed Him, “If you continue in My word, then you are truly disciples of Mine;
32 and you will know the truth, and the truth will make you free.”
33 They answered Him, “We are Abraham’s descendants and have never yet been enslaved to anyone; how is it that You say, ‘You will become free’?”
34 Jesus answered them, “Truly, truly, I say to you, everyone who commits sin is the slave of sin.
37 “I know that you are Abraham’s descendants; yet you seek to kill Me, because My word has no place in you.
38 “I speak the things which I have seen with My Father; therefore you also do the things which you heard from your father.”
39 They answered and said to Him, “Abraham is our father.” Jesus said to them, “If you are Abraham’s children, do the deeds of Abraham.
40 “But as it is, you are seeking to kill Me, a man who has told you the truth, which I heard from God; this Abraham did not do.
41 “You are doing the deeds of your father.”They said to Him, “We were not born of fornication; we have one Father: 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 your father the devil, 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.
Here, we see that Jesus was saying that if they had faith in him, they would be saved, or made righteous and free from sin and death. They say “we are not slaves” but Jesus responds that anyone who commits sin is a slave to sin. Then, they make the point that they are Abraham’s descendants. Jesus says “If you were Abraham’s descendant, you would do what Abraham did”. What did Abraham do? He believed the gospel of Jesus Christ! Jesus is saying if they were truly Abraham’s descendants as God defines it, they would believe in Him. Jesus goes on to say that their father is the devil, thereby demonstrating that being a descendant of Abraham in God’s eyes is not a literal, but spiritual kinship. But take special note of verse 43 of John 8. I used to skip over this verse, but God is showed me the meaning of that verse; Jesus asks – “Why is it that you do not understand?” Then Jesus answers his own question; “it is that you cannot hear my word.” Remember faith comes by hearing and hearing by the word of God (Romans 10:16-17,Isaiah 53:1). Jesus is saying they do not have faith because they do not hear His word, confirming they did not have faith in Him, and then pronouncing them disqualified as children of God and of Abraham, and instead qualified as children of Satan.
Colossians 1:12
giving thanks to the Father, who has qualified usto share in the inheritanceof the saints in Light.
Later in John 8, Jesus confirms that Abraham did indeed have faith in Him:
John 8:56
“Your father Abraham rejoiced to see My day, and he saw it and was glad.”
Another apostle, Peter, also had this view of adoption to the family of Abraham through faith.
1 Peter 3:4
4 but [let it be] the hidden person of the heart, with the imperishable quality of a gentle and quiet spirit, which is precious in the sight of God.
5 For in this way in former times the holy women also, who hoped in God, used to adorn themselves, being submissive to their own husbands;
6 just as Sarah obeyed Abraham, calling him lord, and you have become her children if you do what is right without being frightened by any fear.
John 10 is like John 6:44. People never read on to the “why” of John 6:44 in John 6:64-65
John 6:64-65 (NASB) 64 "But there are some of you who do not believe." For Jesus knew from the beginning who they were who did not believe, and who it was that would betray Him. 65 And He was saying, "For this reason I have said to you, that no one can come to Me unless it has been granted him from the Father."
BECAUSE Jesus knew from the beginning who would & who would not have faith. Because of this foreknowledge he said no one can come unless it is granted. So then the deciding factor on whom will be drawn is whom God had foreknowledge that they would have faith.
1Peter 1:2
[chosen] according to the foreknowledge of God the Father, by the sanctifying work of the Spirit, to obey Jesus Christ and be sprinkled with His blood: May grace and peace be yours in the fullest measure.
