Keep your mind on what you are doing -- and especially WHY you are doing it. As soon as you forget you are doing it for God, it ceases to be for God: the flesh has taken over. The motive of all we do must be an ever-conscious love of God. True, strong love does not forget. It CANNOT forget. Where there is forgetting, love is weak and imperfect. Love is what gives value to the service in God's sight.
