Prayer is truly a heavenly armor, and is alone can keep safe those who have dedicated themselves to God. Prayer is the common medicine for purifying ourselves from the passions, for hindering sin and curing our faults. Prayer is an inexhaustible treasure, an unruffled harbor, the foundation of serenity,the root and mother of myriads of blessings.
–Saint Nektarios of Aegina (1846-1920)
