The Sixties Radical-Azriel

Nobody believed Noah. But Abraham, some say, convinced most of his generation.

Noah talked as someone who followed a tradition of the past. Abraham described how he had discovered G‑d on his own.

Only once you have made it your own, then you can give it to others.

Likutei Sichot vol. 20, pg. 13ff
