When the time comes, and especially the time put aside for God and His temple, a feast day or the hour of Divine Services, hurry to tear yourself away from business and worldly cares and voluntarily and zealously offer yourself to God in His church. When you enter the church bring to mind the promise of the Lord to those that gather in His name: "there am I in the midst of them" (Matt. 18:20), and stand reverently in church, as before the very face of Christ, and pray to Him that He sanctify you by His holiness, animate you by His prayer, and enlighten you with the word of the Gospel and the Grace of the Mysteries. Take note of this, too: in the church, angels serve with us and guard the holiness dwelling there. Once, in the Lavra of Saint Theodosius near Jerusalem, Abba Leontius, coming one Sunday to church to receive the Holy Mysteries, saw an angel standing on the right side of the Holy Table, and when the elder, being afraid, turned to run to his cell, the voice of the angel called to him: "From the time this Holy Table was consecrated, I have been charged to stay by it." Remember this, beloved, and stand reverently. And, if you feel that only your body is standing in church, while your mind thinks of home, or the market, or a place of merriment, collect yourself. Hurry to bring back your mind that has strayed, join it to God in your heart, force it to strive towards God, Who looks upon you. When you hear the word of God, open up not only your bodily ears, but your spiritual ones as well, open your heart, receive this heavenly Bread and with it nourish not only your memory, but also your life and work.
When you are preparing to be a communicant of the Body and Blood of Christ, or are simply present at this Mystery, cleave in mind and heart to the Cross and the Tomb of the Lord, to the Body of Christ, suffering, dying, buried, risen, glorified and believe that your faith's touching Him will be more substantial than the touching of His garment by the woman with an issue of blood, and Christ's power [will] go out (Luke 8:46) to purify and elevate your powers of soul and body.
