Archimandrite Zacharias of Essex
Pain of heart is therefore of great value in the practice of prayer, for its presence is a sign that the ascetic is not far from the true and holy path of love for God. If God, through suffering, showed His perfect love for us, similarly, man has the possibility, through suffering, to return his love to God.
Consequently, prayer is a matter of love. Man expresses love through prayer, and if we pray, it is an indication that we love God. If we do not pray, this indicates that we do not love God, for the measure of our prayer is the measure of our love for God. St. Silouan identifies love for God with prayer, and the Holy Fathers say that forgetfulness of God is the greatest of all passions, for it is the only passion that will not be fought by prayer through the Name of God. If we humble ourselves and invoke God’s help, trusting in His love, we are given the strength to conquer any passion; but when we are unmindful of God, the enemy is free to slay us.
