Prayer draws into the soul the Holy Spirit, and raises man to Heaven. The Fear at the End of Life, 370AD You victorious martyrs who endured torments gladly for the sake of the God and Savior, you who have boldness of speech toward the Lord himself, you saints, intercede for us who are timid and sinful men, full of sloth, that the grace of Christ may come upon us, and enlighten the hearts of all of us that so we may love him. Commentary on Mark, 370AD Lord, shed upon our darkened souls the brilliant light of your wisdom so that we may be enlightened and serve you with renewed purity. Sunrise marks the hour for men to begin their toil, but in our souls, Lord, prepare a dwelling for the day that will never end. Through our unremitting zeal for you.
