The name Barabbas means “son of the father” (bar-abba). Before Pilate and the crowd, there were two sons of the father, one innocent, one guilty. They chose one to free, one to condemn.
Which son of the father was Adam, and the rest of us, suppose to be like?
Two sons of the father, that makes them brothers, family. The Father did not condemn either son. We did. And the elder Son came to save the younger son.
