TSK · Genesis 15:6

For what does the Scripture say? "Abraham believed God, and it was accounted to him for righteousness."

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.

namely, that God was in Christ reconciling the world to himself, not reckoning to them their trespasses, and having committed to us the word of reconciliation.

By faith, Abraham, when he was called, obeyed to go out to the place which he was to receive for an inheritance. He went out, not knowing where he went.
