"The action of the Jesus Prayer is always hidden by the greatest mysteries. It does not consist merely in speaking the words, 'Lord Jesus Christ, Son of God, have mercy on me, a sinner.' but reaches the heart and mysteriously settles there. Through this prayer we enter into relationship with the Lord Jesus Christ, we become accustomed to Him, we merge with Him into one whole. This prayer fills the soul with calm and joy amidst the most difficut trials, in the midst of every oppressions and human vanity." St. Barsanuphius of OptimaIt is a prayer which demands and aids in our focusing of the attention of our mind on our sinful state and our need for forgiveness by God.
"The essential properties of this prayer should be: attention ,the enclosure of the mind in the words of the prayer, extreme unhurriedness in pronouncing it, and contrition of spirit.... In the case of the Jesus Prayer, the mind is concentrated on a single thought: the thought of the sinner's forgiveness by Jesus." St. Ignatius BrianchaninovThrough the practice of this prayer which involves many repetitions each day we are aided in developing of humility calling into us the Holy Spirit to transform our inner being into one of divine joy.
If we want to realize and know the truth... let our aim be to make the energy of prayer alone active in our hearts, for it brings warmth and joy to the spirit, and sets the heart alight with an effable love for God and man. It is on account of this that humility and contrition flow richly from prayer. For Prayer in the beginners is the unceasing noetic activity of the Holy Spirit. To start with it rises like a fire of joy from the heart; in the end it is like light made fragrant by Divine Energy. St. Gregory of SinaiFor me personally, the Jesus Prayer has transformed my life. For many years I denied my sinfulness, but now it is ever before me. I now struggle with contrition, but with hope and an inward burning zeal. I ask for your prayers.
