The Jesus Prayer – Its Power and Purpose

Part 3: Prayer and Watchfulness (Nepsis)

3.1: The Jesus Prayer – Its Power and Purpose

Opening Reflection

The Jesus Prayer—“Lord Jesus Christ, Son of God, have mercy on me, a sinner”—is at the heart of Orthodox spiritual life. For the Fathers, it was not just a form of prayer but a means of inner purification, communion with Christ, and transformation of the heart.

The power of this short request lies in its simplicity, theological depth, and its ability to be prayed unceasingly (1 Thessalonians 5:17). In this lesson, we explore the origins, meaning, power, and practical application of the Jesus Prayer in the ascetical life.

1. The Origins and Biblical Foundation of the Jesus Prayer

Though the formula developed over time, its essence is biblical:

• “Lord Jesus Christ” affirms His divinity and lordship; “ይህም በሰማይና በምድር ከምድርም በታች ያሉት ሁሉ በኢየሱስ ስም ይንበረከኩ ዘንድ፥ መላስም ሁሉ ለእግዚአብሔር አብ ክብር ኢየሱስ ክርስቶስ ጌታ እንደ ሆነ ይመሰክር ዘንድ ነው።” (Philippians 2:10–11).
• “Son of God” affirms His unique relationship to the Father; “እኔም አይቻለሁ እርሱም የእግዚአብሔር ልጅ እንደ ሆነ መስክሬአለሁ።” (John 1:34).
• “Have mercy on me” echoes the blind man’s plea; “እርሱም፦ የዳዊት ልጅ፥ ኢየሱስ ሆይ፥ ማረኝ እያለ ጮኸ” (Luke 18:38).
• “A sinner” reflects the tax collector’s humble cry “God, be merciful to me, a sinner!”; “ቀራጩ ግን በሩቅ ቆሞ ዓይኖቹን ወደ ሰማይ ሊያነሣ እንኳ አልወደደም፥ ነገር ግን፦ አምላክ ሆይ፥ እኔን ኃጢአተኛውን ማረኝ እያለ ደረቱን ይደቃ ነበር።” (Luke 18:13).

Early Use: St. John Cassian (4th century) recommended a similar short prayer. Later, the Desert Fathers, and most deeply the Hesychasts or Ascetics (especially on Mount Athos), gave it central importance.

2. The Power of the Name of Jesus

The Church Fathers teach that the Name of Jesus is filled with divine energy and grace.

“The name of Jesus, once inscribed in the heart, becomes a source of joy and light.”— St. John Climacus, The Ladder of Divine Ascent.

“There is no other name under heaven given to men by which we must be saved.” — Acts 4:12

The Jesus Prayer is not magic or a mechanical formula. It is a cry of the heart, an act of faith, humility, and love. It is also an expression of repentance, aligning the soul with God’s mercy.

3. The Purpose of the Jesus Prayer

The purpose is not just to say the words, but to:

• Still the mind and descend with the prayer into the heart (inner stillness).
• Purify the thoughts and silence the passions.
• Establish constant communion with Christ.
• Practice continual repentance and remembrance of death.

When practiced properly and diligently, the Jesus prayer becomes part of your breath, your heartbeat, your very being—leading to unceasing prayer, as taught by St. Paul (1 Thess. 5:17).

“Let the remembrance of Jesus be united to your every breath.”— St. Hesychius of Jerusalem.

4. The Jesus Prayer and the Path to Theosis

By calling on the Name of Jesus with a repentant heart, we gradually become transformed into His likeness. The Jesus Prayer is not an end in itself, but a means to union with God (theosis).

It:

• Sanctifies the mind and heart,
• Burns away pride and impurity,
• Makes the soul receptive to divine grace.

“The sun shines on the face of the earth; the Name of Jesus shines continually in the soul.”— St. Barsanuphius the Great.

5. Practical Guidance from the Fathers

The Fathers gave clear and simple directions for practicing the Jesus Prayer:

• Pray with attention and humility.
• Sit quietly with the prayer rope (መቁጠርያ), repeating the prayer slowly.
• Breathe calmly, aligning each phrase with your breath:
• “Lord Jesus Christ” (inhale),
• “Son of God” (pause),
• “Have mercy on me, a sinner” (exhale).

“Let the prayer penetrate your heart, and let it not depart from your lips.”— St. Theophan the Recluse.

• Avoid forcing feelings or visions. This leads to delusion (false belief). The goal is purity and watchfulness (attention), not spiritual impression.

6. Testimonies of the Saints

• St. Silouan the Athonite prayed the Jesus Prayer unceasingly and taught that humility and love are its fruits:
• St. Gregory of Sinai taught that with patient effort, the prayer roots itself in the soul and brings light.
• St. Seraphim of Sarov practiced the Jesus Prayer day and night, leading to his radiant joy and peace.

7. Common Struggles and Encouragement

It is normal to face:

• Wandering thoughts (Tempting thoughts),
• Dryness or spiritual fatigue,
• Temptations to give up.

Proceed in your prayers. Even when the prayer feels dry, it is silently sanctifying your soul. Like water shaping a stone drop by drop, the Jesus Prayer slowly engraves the image of Christ in you.

“You become what you pray.” — St. Porphyrios. (Eastern Orthodox Saint)

Conclusion:

The Jesus Prayer is a way of life, not just a method. It teaches us to walk humbly, remain watchful, and dwell in God’s mercy. It is both sword and shield in the spiritual struggle—cutting through demonic thoughts and guarding the soul in peace.

“Lord Jesus Christ, Son of God, have mercy on me, a sinner.”— Let this be the breath of your soul.
