By praying “Lord Jesus Christ, have mercy on me” you will earn everything. Through prayer man is purified, brightened, sanctified.
Prayer is the lifebelt of the soul and the body. Prayer is the basis of perfection. You will become delicate and light, be able to fly, through prayer.
There is no other way of salvation, cleansing, and sanctification than mental prayer. Prayer has filled heaven with holy people.
Elder Amphilochios Makris
