A man standing on the seashore sees the immense expanse of water, but his eye can embrace only a small part and cannot reach its limit. In the same way, a man who, through contemplation, is given to see the limitless ocean of Divine glory and to see God Himself with the eyes of his mind, sees God and the infinite vastness of His glory, though not the whole as it really is, but only as much as is possible for him.
The experience of the ages shows that the sign of the cross has great power over all a person’s actions during the entire course of his life. Therefore it is necessary to strive to root in children the habit of protecting themselves with the sign of the cross often, especially when receiving food and drink, going to bed and waking up, before departing somewhere in a vehicle, before leaving and entering any place; and they should not make the sign carelessly or according to fashion, but precisely, beginning with the forehead to the solar plexus, then to both shoulders, so that a proper cross is produced.... The sign of the cross has saved many from great dangers and afflictions.
Pray before your body takes rest on your bed... If you are tempted, make the Sign (of the Cross) on your forehead reverently… for this is a known and tested weapon against the Devil.
Unless the inner man meditates upon the law of God and is nourished thereby, unless he is strengthened by reading and by prayer, he is conquered by the outer man, and he serves his master.
