What I have learned from Jewish life is that if a man is not more than human, then he is less than human. Judaism is an attempt to prove that in order to be a man, you have to be more than a man; that in order to be a people, we have to be more than a people. Israel was made to be a “holy people.” This is the essence of its dignity and the essence of its merit. Judaism is a link to eternity, kinship with ultimate reality.—Abraham Joshua Heschel in Moral Grandeur and Spiritual Audacity: Essays, 6–7
If that is true of Judaism (and I'm sure it is), then it is even truer of Christianity. Would that those of us who call ourselves "Christians" would live like we believe it!
And that is truly possible by the power of the Holy Spirit!
