We know that prayer in and of itself cannot save us, but carrying it out before God can. For when the Lord's eyes are upon us He sanctifies us, as the sun warms everything upon which it shines.
Gregory PalamasMore Gregory Palamas quotes
Let no one out of laziness or continuous worldly occupations miss these holy Sunday gatherings, which God Himself handed down to us, lest he be justly abandoned by God... If you are detained and do not attend on one occasion, make up for it the next time, bringing yourself to Christ's Church. Otherwise you may remain uncured, suffering from unbelief in your soul because of deeds or words, and failing to approach Christ's surgery to receive... holy healing.
Gregory Palamas
