Dr. Alexander Harb – The Kingdom of the Heart: Meditations from the Christian East on Inside the Pages with Kris McGregor

Dr. Alexander Harb and Kris McGregor explore The Kingdom of the Heart: Meditations from the Christian East, his new book that gives both spiritual and theological insight into Eastern Christian spirituality through the lens of the Desert Fathers and the Philokalia. Dr. Harb draws from his Melkite upbringing to describe how Eastern Christianity puts prayer and transformation toward the heart—an inner stillness cultivated through asceticism and the Jesus Prayer. This tradition invites us to unite our hearts with Christ’s, not just in theory but through lived compunction, metanoia (inner conversion), and deep emotional engagement with God’s love. True knowledge of God isn’t just academic but relational—akin to the intimacy of family—and how early monks wept not out of guilt, but out of being overwhelmed by divine love.
The roles of mercy, trust, and detachment from worldly distractions are essential to guarding the heart. Bright sadness—a concept from Eastern Lent—captures the paradox of Christian sorrow infused with hope. Finally, the discussion circles back to Christ’s own battle with temptation in the desert, illustrating how scripture and silence anchor the soul in times of trial. Dr. Harb’s book invites us into a journey of inner transformation with divine intimacy, wisdom born of suffering, and a deep call to holiness.
Discerning Hearts Reflection Questions:
- How is God inviting me to place my mind in my heart during prayer?
- In what ways have I experienced metanoia as more than just repentance, but a turning of my whole self toward Christ?
- Do I allow Jesus to truly love me in my brokenness, or do I hide behind shame or pride?
- What role does compunction—sorrow for sin born of love—play in my spiritual life?
- How can I better guard my heart from the noise, anxieties, and distractions of the world?
- Am I allowing the Jesus Prayer or similar practices to bring silence and stillness into my prayer life?
- What does spiritual fatherhood (or motherhood) look like in my vocation, and how am I being formed in it?
From the book’s description:
“Although the story of our salvation began in the Orient, the richness of the spirituality of our Eastern Fathers and Mothers in the Faith has long remained hidden. The Church is indebted to the East for revealing how Christians from apostolic times lived their faith, from founding Christian monastic life to developing the worship that has helped shape our liturgy.
In this spiritual masterpiece, Dr. Alexander Harb offers penetrating meditations on nine themes of the spiritual life, drawing from Eastern Christian sources and his own real-life examples. Each chapter includes a power-packed meditation, a related Scripture passage, engaging reflection questions, and challenges that are perfectly accessible for individual or group study.
Through the lens of the Eastern Church and the Desert Fathers, you will reflect on topics such as repentance, the Jesus Prayer, heartbrokenness, discernment, family, friendship, and total reliance on God.
In these absorbing pages, you will discover:
- Advice on building virtue and accepting the love, life, and fire of the Holy Spirit
- Tips on entering into the stillness of prayer and reorienting yourself when distractions arise
- The four stages of conversion and three stages of prayer, according to the Eastern Fathers
- Ways to discern spirits, and simple yet rich wisdom to help you in times of temptation
- How to encounter God’s peace more deeply in the liturgy and how to worship Him more fruitfully
- Methods of attaining metanoia, cardiagnosia (knowledge of the heart), and true transformation
Although practicing asceticism can be challenging, the fruits of inner freedom, peace, and the vision of God are unmistakable. These life-changing reflections aim to help you experience God’s compassionate and healing love for you and your family. By absorbing the wisdom of the East, you will come to know the Father’s merciful love more deeply, grow closer to our Lord, Jesus Christ, and become enlightened by the Holy Spirit.”
