“Whoever battles with monsters had better see to it that it does not turn him into a monster” (Nietzsche). A God-fearing man once complained to a sage that he was tormented by evil desire and had become despondent over it. The sage listened intently and then said, “Guard yourself from such despondency above all else, for it is worse than sin. When the yetzer [evil impulse] awakens desire in us, it is not concerned with plunging us into sin, but with plunging us into despair by way of our sinning.”
We recall the words of James the Righteous: “Each person is tempted when he is lured and enticed by his own desire. Then when desire has conceived, it gives birth to sin; and sin when it is fully grown brings forth death. Do not be deceived…” (James 1:14-16). In other words, sin begins with selfish desire, but the “fruit” or “end” of sin is death, understood as separation from life, healing, love, peace, and so on. Sin “crouches” at the door; its desire is for you, but you must master it (Gen. 4:7).
