James Finlay writes, in the Centre for Action and Contemplation article 'The Mercy of Littleness':
At the beginning of Thérèse of Lisieux’s autobiography Story of a Soul, she admits that she wondered for a long time why God raises some people to the level of sainthood “who had offended Him” and seemed to have God’s graces forced upon them, having “no obstacle in their way when coming to Him.” Her wrestling is relatable in a world where success, fame, and comparison place us on a scale of worthiness and often lead to self-judgment. But then, Thérèse says, Jesus set before her the book of nature — a vast field of flowers in which “the splendor of the rose and the whiteness of the Lily do not take away the perfume of the little violet or the delightful simplicity of the daisy.”
Hence known to us as the “Little Flower,” Thérèse continues: “And so it is in the world of souls, Jesus’ garden. He willed to create great souls comparable to Lilies and roses, but He has created smaller ones and these must be content to be daisies or violets destined to give joy to God’s glances when He looks down at his feet. Perfection consists in doing His will, in being what He wills us to be.” Thérèse’s insights are reflective of Thomas Merton’s words a half-century later: “For me to be a saint means to be myself. Therefore the problem of sanctity and salvation is in fact the problem of finding out who I am and of discovering my true self.”
This remarkable awareness by a young French Carmelite nun, who was steeped in the writings of fellow Carmelite forebears St. John of the Cross and St. Teresa of Ávila, reminds us that life should not be oriented around climbing to a place of importance. Instead, we discover who we are in Christ through the ordinariness of our lives. As Fr. Richard Rohr learned from Paula D’Arcy, “God comes to us disguised as our life.” Thérèse looked at her life and spiritual path and found them to be little, ordinary, and unremarkable. St. John of the Cross experienced his dark night of the soul amid imprisonment, Teresa of Ávila explore her interior castle amid sickness and ecstatic visions, and Thérèse discovered her Little Way as a daisy in a field of lilies and roses.
The Jesus Prayer, it seems to me, exists precisely in that space of littleness and mercy. As Jesus himself once said "I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children." (Luke 10:21 NIV). The Prayer is simple, no more than 12 words, and to pray it asks no more of us than merely to silently repeat the words Lord Jesus Christ, Son of God, have mercy on me, a sinner.
We cannot know the results of our prayer. We are not praying for anything tangible, so we can't tell if we've received it or not. There is no special technique involved, so that we might know if we've mastered it or not. We are not aiming for an altered state of consciousness, so that we might be able to discern whether we've achieved our goal. We are simply sitting quietly and saying the Prayer in the silence, expecting nothing. It is the plainest and smallest of disciplines, and all it asks is mercy.
