Please read these verses carefully.
"just as Abraham 'believed God, and it was counted to him as righteousness?' Know then that it is those of faith who are the sons of Abraham. And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel" beforehand to Abraham, saying, "In you shall all the nations be blessed." So then, those who are of faith are blessed along with Abraham, the man of faith."
Galatians 3:6-9 ESV
"And because you are sons, God has sent the Spirit of his Son into our hearts, crying, 'Abba! Father!' So you are no longer a slave, but a son, and if a son, then an heir through God."
Galatians 4:6-7 ESV
"You, however, are not in the flesh but in the Spirit, if in fact the Spirit of God dwells in you. Anyone who does not have the Spirit of Christ does not belong to him."
Romans 8:9 ESV
