“The purpose of human life is communion with God, which is the salvation of our souls—their eternal beatitude. And the means of fulfilling His commandments: submission to His will, which reveals itself in the circumstances of life; labor: the purification of the heart from passions; and humility that leads to faith, to accepting His grace, without which nothing good or holy can be accomplished in us. “
(St. Arsenia of Ust-Medvedits, ‘Spiritual Instructions’ in pravoslavie.ru)
