THE FORTRESS™
At Global Bridges
Rescue. Restore. Raise Up.
The Fortress is the discipleship and leader training program of Global Bridges.
You were made to know truth and live by it
At The Fortress, we start with truth and build from there. You will be stretched beyond anything you have experienced in your walk with Christ so far, but you will not face it alone. You will grow alongside believers who share your values and your calling to live out the Great Commission in every part of life, from your own home and community to the ends of the earth.
Substance. Clarity. Courage. That is what a fortress is built from, and here we build it together.
How It Works
One Meeting
Join a weekly group of 10 like-minded Christians led by a trained theologian. You’ll learn professional grade techniques to interpret Scripture rightly and advanced theological concepts that will allow you to address the challenges that your Christian community faces.
One Reading
Each week, we engage with one theological work that stretches your mind, challenges your assumptions, encourages spiritual growth, and builds a robust biblical worldview.
One Action
You don’t just learn—you share. Fortress members create short videos that answer theological questions or explain key truths, turning learning into influence.
One Fortress
This is more than a class. It’s a spiritual forge. You’ll grow into a leader whose life and words reflect the courage, clarity, and conviction of Christ.
Choose your fortress path
Fortress Core
The ideal starting place for those who wish to grow in their knowledge of the core truths that make up the Christian faith. The Core is your journey through systematic theology covering topics such as the nature and character of God, the divinity and humanity of Christ, the End Times, and so much more.
Fortress Apologetics
We don’t just stop at knowing truth, at the Fortress we believe that all Christians should be able to defend truth. This is the goal of Fortress Apologetics. With courses in creationism, biblical justice vs social justice, faith & politics, and identity, you will learn how to confidently stand against the rising tide of secular culture and uphold a biblical worldview.
Fortress Biblical Counseling
Fortress Biblical Counseling is a community of believers who seek to address the difficulties of this world with the hope that only Scripture can provide. We seek to train up helpers who go deeper than the surface and desire to learn how to address the problems caused by sin and brokenness at the root. This isn’t the fluff that secular psychology peddles, this is the truth of Scripture that we are called to remember and live by.
Fortress Missiology for the Suffering Church
The church in much of the world does not grow in comfort. It grows under pressure, in places where following Christ costs something real. Missiology for the Suffering Church asks what Scripture teaches about that, and what it means for carrying the good news into hard places. We study the biblical theology of suffering and witness, the pattern of the early church under Rome, and how believers disciple one another and multiply congregations where buildings, budgets, and public gatherings are not available. This is not a course in strategy. It is about what endures when everything else has been stripped away.
