TSK · Galatians 3:9

He received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision, that he might be the father of all those who believe, though they might be in uncircumcision, that righteousness might also be accounted to them.

but for our sake also, to whom it will be accounted, who believe in him who raised Jesus, our Lord, from the dead,

that the blessing of Abraham might come on the Gentiles through Christ Jesus; that we might receive the promise of the Spirit through faith.

Now we, brothers, as Isaac was, are children of promise.
