1) verse 12: Those who received Christ through faith are justified and adopted as children of God
2) verse 13: Explains how it happened by first telling how it didn’t happen. It didn’t happen by blood through ancestry. It didn’t happen by the will of the flesh, which is to say that unregenerate man cannot quicken his own nature. It didn’t happen by the will of man period. HOW did it happen? Those who believed were born of God. God had intervened and imparted spiritual life and a new nature (2 Cor 5:17). This is also shown in the following passages:
Colossians 2:13 And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses,
God made these sinners alive who were dead and unresponsive.
Ephesians 2:4-5 But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—
God acted and made dead sinners alive while they were still spiritually dead. Sinners do not make themselves alive and come to faith and then have God cause them to be born again and give them a new nature. This would be like a Doctor withholding treatment until a patient got well and then giving them the medicine they needed to be cured. No, without God’s regenerating cure of making sinners spiritually alive, sinners would not respond. However, all (100%) that God regenerates are brought to spiritual life and willingly respond in faith (John 6:37). Jesus compares regeneration to the wind in John 3:8 The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.” No one knows where it comes from or where it is going. This rules out the view that man achieves faith and God responds by then being obligated to regenerate the new believer. This view contradicts Jesus and would amount to man getting himself born again by his own wise free will decision of faith. That is why Paul says in Romans 9:16 So then it depends not on human will or exertion, but on God, who has mercy.
If man controls his own regeneration, then Jesus would have said, “the wind blows where man decides by believing in me and we know it goes to all who believe in me.” But he didn’t. He said the wind like the Spirit goes where IT wishes. Brethren this is the TRUE FREE GRACE of the gospel of Jesus Christ. If you have not received this grace, then don't delay. Repent and believe in Jesus Christ today!
