Judaism: The Temple Institute: The First Jew
To bless and to be a blessing:
When G-d told Avraham to leave all he knew and go to Canaan, it was for much more than simply Avraham staking out his future progeny's claim to the land of Israel.
It was so that Avraham could be a conduit and a portal for G-d's blessings for the family of man.
And so they have been.
