"LOVE MOTIVATED BY MERE DUTY CANNOT HOLD OUT FOR VERY LONG. AND LOVE THAT IS ONLY MOTIVATED BY FAVORABLE CONDITIONS CAN NEVER BE ASSURED OF SUFFICIENT OXYGEN TO KEEP IT BREATHING. ONLY LOVE THAT IS LIFTED UP AS AN OFFERING TO GOD -RETURNED TO HIM IN GRATITUDE FOR ALL HE HAS DONE - IS ABLE TO SUSTAIN ITSELF WHEN ALL OTHER REASONS HAVE LOST THEIR ABILITY TO ENERGIZE US." The Love Dare

in other words - we must love because it is our duty! God created us for this - and we will never survive without Him and his love!
