God is what limits mankind, who makes a comedy of his care, who allows his longing to miscarry, who casts him into solitude, who sets a limit to his knowing and doing, who calls him to duty, and who gives the guilty over to torment. And yet at the same time it is God who forces one into life and drives him into care; who puts longing and the desire for love in his heart; who gives him thought and strength for his work and who places him in the eternal struggle between willfulness and duty. God is the enigmatic power beyond time, yet master of the temporal; beyond existence, yet at work in it.
