Luke 19:9

“And this woman, being a daughter of Abraham, whom Satan has bound for—behold—eighteen years, should she not have been released from this bond on the Sabbath day?”

“And he cried out and said, ‘Father Abraham, have mercy on me, and send Lazarus so that he may dip the tip of his finger in water and cool off my tongue, for I am in agony in this flame.’

“But he said, ‘No, father Abraham, but if someone goes to them from the dead, they will repent!’

and he received the sign of circumcision, a seal of the righteousness of the faith which he had while uncircumcised, so that he might be the father of all who believe without being circumcised, that righteousness might be counted to them,

For this reason it is by faith, in order that it may be according to grace, so that the promise will be guaranteed to all the seed, not only to those who are of the Law, but also to those who are of the faith of Abraham, who is the father of us all—

so know that those who are of faith, those are sons of Abraham.
