Archimandrite Sophrony, Tr. by Rosemary Edmonds. The monk of Mt. Athos: Staretz Silouan 1866-1938 (Crestwood, New York: St. Vladimir’s Seminary Press, 1989), 51-52.
... [M]an in his everyday life is confronted with an endless complexity of situations, and very often does not see what to do to comply with God’s will.
The man who has the love of God in his heart, prompted by this love, acts in accordance with dictates which approximate to the will of God. But they only approximate: they are not perfect. The unattainableness of perfection obliges us all continually to turn to God in prayer for understanding and help.
Not only perfect love but complete knowledge is out of our reach. An act performed, it would seem, with the very best intention often has undesirable and even evil consequences because the means employed were bad, or simply mistaken. People are often heard to justify themselves by saying that their intentions were good. But good intentions are not enough. Life abounds with mistakes of this kind. That is why the man who loves God never ceases to ask Him for understanding, and has a constant ear for the sound of His voice.
