“Do not let pass any opportunity to pray for anyone, either at his request or at the request of his relatives, friends, of those who esteem him, or of his acquaintances. The Lord looks favorably upon the prayer of our love, and upon our boldness before Him. Besides this, prayer for others is very beneficial to the one himself who prays for others; it purifies the heart, it strengthens faith and hope in God, and it enkindles our love for God and our neighbor. When praying, say thus: “Lord, it is possible for You to do this or that to this servant of Yours; do this for him, for You are merciful and almighty.”
Saint John of Kronstadt
