We Write - Because the Church Needs the Resources
Every book David Thomas has written is a growing library of biblically grounded, practically structured resources that serve the individual believer, the ministry team, and the local church.
The Art of Personal Spiritual Warfare
A seven-book series covering the full landscape of spiritual warfare: planning and preparation, allies and enemies, weapons and tactics, and hand-to-hand combat.
This series is the textbook spine of Life House Ministries' Level 2 training programme.
Reconciliation, Deliverance, and Ministry: The Application of the Work of the Cross of Christ
A three-part field manual for the application of the completed work of the Cross into a believer's life, covering restoration, inner healing, biblical deliverance, and practical ministry tools.
This is the ministry foundation beneath everything Life House does.
A Boy's Rite of Passage: From Boys to Men
A practical, countercultural, and biblically grounded roadmap for the journey from boyhood to godly manhood.
Written for boys, parents, and mentors alike.
Finding a Discipleship Environment
A free resource for every believer who has ever sensed that the environment around them was quietly extinguishing, rather than igniting, their growth in Christ.
More titles are currently in preparation, including resources on deception, the end times, A Girl's Rite of Passage, and more.
We Train - Through Calvary Bible School
Calvary Bible School is the training arm of Life House Ministries, in partnership with Water Brook Church - a structured, three-level discipleship programme designed to take a believer from new convert to mature leader, covering every facet of the disciple's life: spiritual, character, ministry, and family.
The school is built on the conviction of Ephesians 4:11–13: that the fivefold ministry exists for one purpose - as a gift from the Head of the Church, Jesus Christ, to equip the saints for works of service until every believer attains the fullness of Christ. It is also built on the conviction of John 10:10b that this fullness is not a theoretical destination, but a lived reality - available now, worth fighting for, and accessible to every believer who is placed in the right environment and given the right training.
Level 1 - Foundations
Free. Self-paced and accessible to any believer, anywhere, at no cost.
Four modules covering the elementary teachings of Christ from Hebrews 6:1–2, the doctrines of the Bible, biblical hermeneutics and exegesis, and an introduction to discipleship. Level 1 is the gateway to everything else.
Level 2 - The Big 5
The core of the Life House training programme. Five essential areas of formation: Intimacy with God, Living from Your Heart, Living in Your Calling, End Times, and Spiritual Warfare. Available online or delivered in person by David, Carolyn, and their teams. Optional intensives include Inner Healing, Men's Boot Camp, and Women's Boot Camp.
Level 3 - Leadership Formation
Senior-level formation for those moving into eldership, apostolic ministry, and church planting. Module list is currently being finalised.
Five Non-Negotiables for the Mature Disciple
The Big 5 is not a checklist.
It is a framework for formation - five interconnected areas that, when developed together, produce the kind of disciple the enemy actually fears.
- One who knows God intimately
- One who lives from the heart rather than from wounds
- One who walks in a God-given calling
- One who understands the hour they are living in
- One who knows how to fight
Intimacy with God
The foundation of everything.
Not a discipline to maintain, but a relationship to live in - a real, daily, growing fellowship with the Father, Son, and Holy Spirit that shapes every other area of the disciple's life.
Everything flows from here - or nothing flows at all.
Living from Your Heart
Formation, not performance. Identity, not striving.
The disciple who does not know their own heart will be governed by it - wounded, reactive, and unable to sustain the life of obedience God calls them to.
This module addresses the inner life with honesty, biblical depth, and genuine pastoral care. Built on the book and training manuals Reconciliation, Deliverance, and Ministry, it trains believers to apply the completed work of the Cross of Christ to their own lives and to co-administer that work in the lives of those they disciple.
Living in Your Calling
Every believer has been given gifts, a vocation, and a specific place in the Body of Christ.
This is not a luxury for the spiritually advanced - it is the baseline expectation of the Kingdom.
This module equips disciples to identify, develop, and step into their calling with confidence and accountability.
End Times
The Church needs to understand the hour it is living in - not with fear or sensationalism, but with the clear-eyed readiness of a soldier who knows the battle plan.
This module grounds disciples in a biblical understanding of the end times, equipping them to stand firm, think clearly, and live with the urgency the moment demands.
Spiritual Warfare
The capstone of the Big 5 - and the area of training most neglected in the modern Church.
The disciple who does not understand spiritual warfare will be defeated by it.
Built on The Art of Personal Spiritual Warfare series, this module trains believers in the full landscape of the battle: the enemies, the allies, the weapons, the armour, and the tactics of both sides.
We Come to You - Ministry into Local Churches
The school is not only online.
David, Carolyn, and their ministry teams travel to local churches to run Level 2 modules in person - from a single weekend session to a week-long intensive, depending on the church's needs and the team's availability.
These visits are not speaking engagements. They are training deployments - designed to leave the local church with tools it can continue using long after the team has gone home.
If your church is hungry for genuine discipleship culture, spiritual warfare training, inner healing ministry, or the Big 5 programme, a Ministry Invitation is open.
What we DO
- Serve under the local senior pastor's authority and vision.
- Train and equip - never replace existing leadership.
- Teach the Big 5 in line with the church's distinctives.
- Hand back tools the local team can keep using.
- Pray for the church and its leaders - before, during, after.
What we DO NOT do
- Recruit members, leaders, or givers away from the church.
- Critique the local church publicly - ever.
- Charge fixed fees; we accept offerings and cover costs.
- Run parallel ministries inside a church we're invited to.
- Take ministry that doesn't belong to us.
The Podcast
An extensive audio teaching library covering the full landscape of spiritual warfare - available free on Spotify, iTunes, YouTube, and other major platforms.
If you are new to the ministry, the podcast is one of the best places to begin. It gives you David's teaching voice, pastoral directness, and a thorough grounding in the subject matter before you dive into the books or training courses.
The Vision
We exist for the glory of God, and for the extension of His Kingdom, to be His disciples, and to train up disciples.
Our mission is to make Christians and the Church more effective, to prepare the Body of Christ for the hour that is coming, and to reach the lost with the only message that has ever truly set humanity free - the message of the cross of Christ. We do this through discipleship that forms soldiers, training that equips combat medics, and a Gospel that advances the Kingdom - one life, one family, one nation at a time.
To make Christians and the Church more effective
Disciples are to be soldiers, not passengers, equipped for the mission of Christ.
To prepare the Body of Christ for the end times
Grounding believers in the Word, the weapons, and the wisdom needed to stand firm in an increasingly dark world.
To reach the world with the Gospel of the Kingdom
The only message that sets humanity free from the law of sin and death, and the only mission worth giving a life to.
The Church needs combat medics.
The nations need the Gospel of the Kingdom.
Life House Ministries exists to produce all three.
