Galatians 3:7-9

Be assured, then, that it is those who live by trusting and being faithful who are really children of Avraham.

Also the Tanakh, foreseeing that God would consider the Gentiles righteous when they live by trusting and being faithful, told the Good News to Avraham in advance by saying, “In connection with you, all the Goyim will be blessed.”

So then, those who rely on trusting and being faithful are blessed along with Avraham, who trusted and was faithful.
