“A greater mystery than reality is the concealment of reality.
As has been said:
The glory of God is perhaps the fact that among the rest of Creation there can also be an unbeliever, who denies God even though he lives by the mercy of God and reveals God with every breath of his nostrils or twitch of his finger.
That such a creature should have the capacity to deny the existence of God is an expression of God’s infinite power.”
–Rabbi Adin Steinsaltz
