Ruth’s desire is for leaders and churches to thrive in the mission God has given us and in a growing relationship with Him. Ruth lives with my husband, Peter, in Joliet, IL, a suburb of Chicago, and finds every opportunity to travel across North America to visit her grandkids--and their parents, of course.

Jeff Heerspink—Local Mission Leader

Jeff grew up in one of the many Christian Reformed Churches in Lynden, Washington. After graduating from Lynden Christian, he studied Agriculture at Utah State University and then returned to Lynden to work on a farm. During this time, after a series of events, the Gospel took root in Jeff’s life and propelled him on a journey toward ministry. After doing camp ministry with Sonsation, and an Internship under Jeff Vanderstelt, he served as a Youth Pastor at First CRC in Seattle. Jeff met and married his wife Beth while in Seattle, and together they moved to Chicago to attend Moody Bible Institute, where Jeff studied Family Ministry and Beth studied Communications. Jeff also took a Leadership course at Willow Creek, and attended a small Neighborhood church in the Bridgeport area of Chicago. Jeff and Beth moved to Lincoln to join the Northern Lighthouse CRC staff after doing an Internship in the summer of 2004. Jeff served at the Northern Lighthouse for 10 years before God gave them an opportunity to start a new church in the heart of Lincoln, F Street Neighborhood Church. Today they have 4 kids (Abigail, Josiah, Caleb and Elia) and have moved into the urban core of Lincoln where they serve. You can connect with Jeff at
