The prayer “Lord Jesus Christ, have mercy on me (us) ” is worth a hundred drachmas, one Elder used to say but “Glory to God for everything” is worth a thousand.
One father once said that “sorrows and pains cleanse and polish a man’ soul; there is nothing greater than these, even the prayer of Jesus”.
Elder Tikhon used to tell us that the prayer “Lord Jesus Christ, have mercy on us” is worth a hundred drachmas, while “Glory to God” is worth a thousand (drachmas).
By this he meant that praising God is more valuable than anything, because many times people say the Jesus Prayer when they’re in need of something, but when someone (been) in distress glorifies God, he is a great ascetic.
