Faith & Work Symposium: Practical Gospel Application

Many marketplace leaders have a solid theology of work—that our work is for the glory of God—but desire to be more effective in putting this theology to work on a daily basis. Join Tim Keller, Katherine Leary Alsdorf, Jeff Disher, Raymond Harris and Dave Ridley as they share out of their own experience and provide practical examples and stories, affirming that for Christians there really is no such thing as secular work.

Bring a friend or a co-worker, but be sure to RSVP below as space is limited. We hope you will join marketplace leaders from around the city for this special event.

Tim and Kathy Keller moved to NYC in 1989 to start a church. New Yorkers responded positively, and other leaders in other cities noticed. They asked for help.


City to City was born because ministry leaders needed help to reach the most influential places on earth—cities. Churches in cities are under-resourced and too few while cities are exploding in growth.

Why we exist

City to City exists to help leaders start and strengthen churches to advance the gospel in cities.

How we meet the need

We help churches focus on how the good news of Jesus Christ creates personal and social change. We equip them to address the specific questions of the time and neighborhood, collaborate for the good of the city, and multiply.

How we measure impact

If resourced and trained leaders start churches and churches work together, lives and cities will change through the Holy Spirit. We’ll know it’s working through stories of change and through the number of churches started and churches involved.


You’re invited to join this work. See it up close. Pray for millions of new and strong churches in cities. Give to this work. And invite others to do the same.
