When a man has found the Lord, he no longer has to use words when he is praying, for the Spirit Himself will intercede for him with groans that cannot be uttered.
John ClimacusWe know the utility of prayer from the efforts of the wicked spirits to distract us during the divine office; and we experience the fruit of prayer in the defeat of our enemies.
John ClimacusOur inhuman enemy inspires the thought that God loves mankind, and that He quickly forgives this sin. But when we observe the guile of demons, then we see that after the commission of the sin, they suggest to us that God is a righteous and implacable Judge. The first they say in order to lead us to sin, the second, in order to weigh us down in despair.
