Support John and Marilyn's Ministry


MAF missionaries raise support for a pooled fund out of which MAF covers salary, housing, benefits, and staff-related ministry expenses. MAF exercises discretion over the use of missionary support to carry out its mission and care for its staff.

John and Marilyn Gorenflo are missionaries with Mission Aviation Fellowship, now serving from MAF headquarters in Nampa, Idaho. They served seven years in Kinshasa, Democratic Republic of Congo, Africa—flying medicines, doctors, patients, and pastors in and out of remote villages; installing VSATs (satellite internet links), fixing computers, solar power systems, or troubleshooting wired or wireless distribution systems. John still performs many of those tasks, but in a worldwide capacity. He’s also a part of the Disaster Response team, responding to earthquakes, hurricanes, and other disasters around the world. After returning to the States, Marilyn has served for six years at MAF headquarters as a ministry partnership coach, a mentoring job she very much enjoys. In 2020, she added the role of director of Ministry Partnership. She values the chance to connect with all the MAF departments and with programs around the world. 

A foundational verse in John’s life is, “Trust in the Lord with all your heart and lean not on your own understanding; in all your ways acknowledge Him, and He will make your paths straight,” (Proverbs 3:5-6). John was born into a loving Christian family, accepted the Lord as Savior at age seven, and has always enjoyed the vast world of God’s creation. Born in Huntsville, Alabama, John lived in several states during his school years. He earned a B.S. in aerospace engineering at the University of Tennessee, Knoxville. After college, John served 12 years as a pilot in the Air Force, and he and Marilyn were stationed in England for several years as John travelled and served throughout Europe. 

Marilyn grew up in Virginia and Tennessee, giving her life to Christ at age eight. Over the years, God has drawn her closer to Him, using her Christian parents and many others to speak into her life. Marilyn graduated from the University of Tennessee in English and Spanish after spending a year in Madrid, Spain, as an exchange student. She has taught middle school, high school, and adults, both in the States and in the Congo. Several years ago, she finished her Master of Education, and she also holds a private pilot’s license. “I’ve had a variety of roles over the years, and the key for me has been my willingness to serve God in whatever capacity I can,” Marilyn shares. Marilyn quotes 2 Corinthians 12:9, in which God promises that “My grace is sufficient for you, for My power is made perfect in weakness.”  “This is my reminder to lean on Him rather than rely on my own strength,” says Marilyn. 

Marilyn and John married in 1989 and have three adult daughters, who fondly remember their years growing up overseas. 

God calls the men and women of MAF to serve Him in unique ways. He may also be calling you to a special role in the Gorenflos’ ministry. Please prayerfully consider becoming a ministry partner with them through prayer and/or financial support.
