Sharing the Life of God: A Biblical Introduction to Theosis for Evangelicals
✅ 1. Opening (1–2 minutes)
Introduce the theme:
“Tonight we’re exploring the biblical idea that salvation is not only about forgiveness — it’s about sharing the life of God and becoming like Jesus from the inside out.”
Invite openness:
“Orthodox Christians call this theosis. Evangelicals usually call it sanctification and union with Christ. We’ll look at Scripture and see how the Bible talks about deep transformation.”
✅ 2. Key Idea #1 — What Is Theosis? (5 minutes)
Simple definition (Evangelical‑friendly):
Theosis = God shares His life with us through the Holy Spirit so we can become like Jesus.
This is NOT:
- becoming gods
- merging with God’s essence
- replacing justification
This IS:
- deep transformation
- union with Christ
- participation in God’s life and holiness
✅ Biblical Support
- “Partakers of the divine nature” — 2 Peter 1:4
- Scripture’s clearest statement that believers share in God’s own life.
- “Christ in you, the hope of glory” — Col 1:27
- Christ doesn’t only save us — He dwells in us.
- “We shall be like Him” — 1 John 3:2
- The final goal of salvation is likeness to Christ.
- “Transformed from glory to glory” — 2 Cor 3:18
- Ongoing, Spirit-driven transformation into God’s image.
✅ Discussion Questions
- What does “partakers of the divine nature” mean to you?
- Do these verses suggest transformation is deeper than moral effort?
- How does “Christ in you” shape your understanding of the Christian life?
✅ 3. Key Idea #2 — The 3-Stage Framework (7 minutes)
Explain the Orthodox framework in non-technical, familiar terms:
✅ Stage 1: Purification (Katharsis) — Healing Our Desires
Biblical basis:
- “Put off the old self… put on the new” — Eph 4:22–24
- “Blessed are the pure in heart, for they shall see God” — Matt 5:8
- “Put to death what is earthly in you” — Col 3:5
Evangelical equivalent:
Sanctification begins here — repentance, healing, letting the Spirit reshape us.
✅ Stage 2: Illumination (Theoria) — Renewing Our Minds
Biblical basis:
- “Be transformed by the renewal of your mind” — Rom 12:2
- “The eyes of your heart enlightened” — Eph 1:17–18
- “We have the mind of Christ” — 1 Cor 2:16
Evangelical equivalent:
Hearing God, understanding Scripture, walking in the Spirit.
✅ Stage 3: Union (Theosis Proper) — Sharing God’s Life
Biblical basis:
- “Abide in Me and I in you” — John 15:4–5
- “I no longer live, but Christ lives in me” — Gal 2:20
- “Filled with all the fullness of God” — Eph 3:19
- Jesus’ prayer for union — John 17:21–23
Evangelical equivalent:
Christlikeness, deep union with Christ, Spirit‑transformed living.
✅ Discussion Questions
- Where do you see yourself in these stages right now?
- Which of these feels most familiar? Most unfamiliar?
- How does God do the transforming, and how do we cooperate?
✅ 4. Key Idea #3 — What Are “Divine Energies”? (5 minutes)
Evangelical-friendly explanation:
Divine energies = God’s real, active presence — His love, light, power, and grace — working in us.
This does NOT mean:
- becoming part of God’s essence
- mystical esotericism
This DOES mean:
- the Holy Spirit at work
- transformation from the inside out
- participating in God’s love, holiness, and power
✅ Biblical Support
- “Partakers of the Holy Spirit” — Heb 6:4
→ Not metaphorical: we share in God’s presence. - “God works in you” — Phil 2:12–13
→ Salvation is synergistic: God energizes (“energeō”) His life in us. - “In Him we live and move and have our being” — Acts 17:28
→ God is sustaining and empowering our very existence. - “The love of God poured into our hearts by the Holy Spirit” — Rom 5:5
→ God’s own love becomes our love. - Transfiguration (Matt 17:1–8)
→ Jesus’ divine light revealed — understood by the early Church as God’s uncreated energy.
✅ Discussion Questions
- How do you experience God’s presence working in you?
- What does it mean that God “works in you to will and to act”?
- How does the Holy Spirit empower real transformation?
✅ 5. Putting It Together (3 minutes)
Summarize for Evangelicals:
Theosis = sanctification + union with Christ + empowerment by the Spirit.
It is simply the Bible’s teaching that God doesn’t just forgive us —
He transforms us to share His love, holiness, and life.
This view does not challenge justification by faith.
It expands the meaning of sanctification into a rich, relational, Spirit-filled journey.
✅ 6. Application (2 minutes)
Ask participants:
- Where might God be inviting you into deeper transformation?
- Is there an area where you need purification?
- Is God illuminating something new in your understanding?
- What would it look like to “abide in Christ” more fully this week?
End with a prayer for deeper union with Christ and openness to the Spirit’s work.

Below is a concise but fuller Evangelical‑friendly explanation of katharsis, theoria, and theosis — what they are, what they do, and how Christians actually live them out.
No specialized Orthodox metaphysics needed. Everything is grounded in Scripture, the Holy Spirit, and Evangelical spiritual practice.
✅ 1. KATHARSIS — Purification
What it is (Evangelical-friendly definition):
Katharsis means God healing and cleansing our hearts so that sin loses its power and Christ becomes our deepest love.
Think: early and ongoing sanctification.
It is the part of the Christian life where the Holy Spirit:
- convicts us of sin
- reshapes our desires
- breaks sinful patterns
- forms Christlike character
Biblical support:
- “Blessed are the pure in heart, for they shall see God.” (Matt 5:8)
- “Put off the old self… be renewed… put on the new self.” (Eph 4:22–24)
- “Let us cleanse ourselves from every defilement.” (2 Cor 7:1)
- “Put to death what is earthly in you.” (Col 3:5)
How to live katharsis (practical):
- Confession and repentance
Regularly bringing sins into the light. - Surrender
Yielding habits, desires, and attitudes to God. - Fasting / simplicity
Removing what distracts or enslaves. - Scripture intake
Letting God’s Word renew desires and correct motives. - Community accountability
Letting brothers and sisters sharpen us.
Evangelical analogy:
Katharsis is God detoxing the soul so we can love Him freely and deeply.
✅ 2. THEORIA — Illumination
What it is (Evangelical-friendly definition):
Theoria means Spirit‑given clarity — the renewal of our minds so we see God, Scripture, ourselves, and the world rightly.
Think: deep spiritual insight, hearing God, renewed mind.
Theoria is not esoteric mysticism — it is:
- wisdom
- discernment
- spiritual perception
- Holy Spirit illumination
- the mind of Christ in daily life
Biblical support:
- “Be transformed by the renewal of your mind.” (Rom 12:2)
- “The eyes of your heart enlightened.” (Eph 1:17–18)
- “We have the mind of Christ.” (1 Cor 2:16)
- “Your word gives light.” (Ps 119:130)
How to live theoria (practical):
- Meditation on Scripture
Not just reading, but prayerfully pondering. - Listening prayer
Asking God to reveal His heart and will. - Silence and solitude
Making space to hear and notice God. - Obedient responsiveness
Acting on what God reveals reinforces spiritual clarity. - Worship
Seeing God’s greatness trains spiritual perception.
Evangelical analogy:
Theoria is walking in the Spirit, where God opens your eyes to truth, direction, and His presence.
✅ 3. THEOSIS — Union With God
What it is (Evangelical-friendly definition):
Theosis means sharing in God’s life so deeply that Christ’s character, love, and power flow through us.
Think: Christlikeness, abiding, Spirit-filled life.
Orthodoxy describes theosis as “union with God,”
but Evangelicals can understand it as:
God’s life in us producing God’s likeness through the Holy Spirit.
This is not “becoming gods.”
It is experiencing the fullness of what Scripture calls:
- Christ in us
- abiding in Him
- walking in the Spirit
- being transformed into His image
Biblical support:
- “Partakers of the divine nature.” (2 Pet 1:4)
- “Christ in you.” (Col 1:27)
- “I no longer live, but Christ lives in me.” (Gal 2:20)
- “Filled with all the fullness of God.” (Eph 3:19)
- “That they may be one, as We are one.” (John 17:21–23)
How to live theosis (practical):
- Abiding in Christ
John 15: remain connected to the Vine. - Living from the Spirit, not the flesh
Allowing the Spirit to empower obedience and love. - Practicing Christlike love
Love of enemies, forgiveness, humility. - Sacrificial service
Christ’s life flows through us as we give ourselves away. - Regular surrender and openness
Allowing God’s presence to shape our reactions, motives, and desires.
Evangelical analogy:
Theosis is glorification beginning now — real Christlikeness growing as God’s life flows through us.
✅ Putting It All Together in Evangelical Language
We can describe the 3 stages this way:
✅ Katharsis — God cleanses me
(Sanctification begins)
✅ Theoria — God renews my mind
(Wisdom, discernment, walking in the Spirit)
✅ Theosis — God lives His life through me
(Fullness of union with Christ)
This is not a rigid ladder.
It is a continual cycle in the Christian life:
- We repent
- God clarifies
- God fills
- Then deeper repentance
- Deeper renewal
- Deeper union
Over and over — from “glory to glory” (2 Cor 3:18).
✅ Why Evangelicals Can Embrace This
Theosis =
God transforming us into Christlikeness,
through the Spirit,
by union with Christ,
for the glory of the Father.
It is nothing other than:
- John 15 (abiding)
- Romans 8 (Spirit-led holiness)
- Galatians 2 (Christ lives in me)
- 2 Corinthians 3 (transformation by beholding Him)
- Ephesians 3 (filled with God’s fullness)
- 2 Peter 1 (partakers of divine nature)
It is simply:
The Bible’s vision of sanctification lived at full strength.
