"It has often been said that prayer is the greatest force in the
universe. This is no exaggeration. It will bear constant repetition.
In this atomic age when forces are being released that stagger the
thought and imagination of man, it is well to remember that prayer
transcends all other forces." - F. J. Huegel

"They who pray not, know nothing of God, and know nothing of the
state of their own souls." – Adam Clarke
