Zieg's on a Mission

We Reach the People the Gospel Never Has.

We're Jeremy and Lindsay Ziegenhorn. We serve with Team Expansion, mobilizing, training, and sending the workers who go to people who have never once heard the name of Jesus.

The Number That Keeps Us Up At Night

More than 70,000 people pass away every single day without ever having access to the gospel. Not 70,000 a year. A day.

The harvest was never the problem. Jesus said it plainly: the harvest is plentiful, the workers are few.

That's where we've aimed our lives. Not the shortage of need, but the shortage of trained, sent, fully funded workers to meet it.

WHO WE ARE

In 2012, we started hearing the Great Commission with new ears and reordered our entire lives around it. Through Scripture, prayer, and a few hard conversations, we started seeing the Great Commission for what it actually is. Not a nice idea for the spiritually ambitious. A command with a deadline.

We've lived all three sides of this mission since. Local outreach to international students. Four years making disciples in Italy, with our daughters Zoe and Ava alongside us. And now back in Louisville, training and sending the next wave of workers before they ever reach the field.

Very few people have done all three. That's exactly why we can take you from wherever you are and move you forward.

You’re not just reading a story — you’re stepping into one.

WHAT YOUR PARTNERSHIP MAKES POSSIBLE

Everything we do comes down to three words.

Mobilize. We help believers see the unreached clearly and find their place in reaching them.

Train. We don't graduate workers because a program ran for a few weeks. We train to a standard, and we send them when they're genuinely ready.

Send. We coach missionaries to build sustainable prayer and financial teams, so they launch strong and stay on the field for the long haul.

THE LATEST

We share the real story as it unfolds. The wins, the challenges, and everything in between.

From the blog: The Quiet Heroes Behind Every Missionary

"You don't have to cross an ocean to be essential to what happens on the other side of it. In God's economy, the sender carries as much weight as the one sent."

BECOME PART OF THE 300

We're after one audacious thing. To mobilize, train, and send 300 additional missionaries to the unreached peoples of the world by August 31, 2031.

This is one of the most ambitious sending goals in modern missions, and we mean to hit it. It takes senders. People who pray, give monthly, and stay. Every person who steps in becomes part of those 300.

Wherever you're starting from, there's a place for you in this.
