Lord Jesus Christ, Son of God, Have Mercy on Me, a Sinner.

"Prayer is by its very nature a dialogue and a union with God. Its effect is to hold the world together and to achieve a reconciliation with God. Prayer is the mother and daughter of tears. It is expiation of sin, a bridge over temptation, a barrier against affliction. It wipes out conflict, is the work of Angels and the nourishment of all bodiless beings. Prayer is the future gladness, an endless work, a wellspring of virtues, a source of grace, hidden progress, food for the soul, an illumination of the mind, an axe against despair, a proof of hope, sorrow done away with, the wealth of monks, the treasure of hesychasts, the reduction of anger, the mirror of progress, a demonstration of success, evidence of one's condition, the future revealed, and a sign of glory. For him who truly prays, prayer is the court, the judgment hall and the tribunal of the Lord before the judgment to come." St. John Climacus
