There is Nothing on Earth More Powerful than the Divine Liturgy: A Sermon by St. Seraphim (Zvezdenski)
That you may stand more easily and without distraction during the Divine Liturgy, do the following: while the hours are being chanted, remember the living and departed in your prayers. These commemorations will rise to heaven together with the commemorations being offered by the priest during proskomedia and will bring great consolation to the souls of those remembered. Here it does not matter if the commemorations are made in the altar before the table of oblation, at the doors of the altar, or in the midst of the church, for the Lord is everywhere and hears everything. When the opening exclamation of the Liturgy is made, “Blessed is the Kingdom …” pray that the Lord would grant unto you the Heavenly Kingdom. At the offering of the first litany of peace,((The Great Litany)) pray that the Lord would give you His peace during this day.
