As Tim reflects on his career with MAF, he increasingly realizes that it is truly Christ who is building His Kingdom through his ministry. Tim shares, “I am learning more and more that I cannot accomplish anything for God by my own efforts, but only through the power of God’s Holy Spirit working through me.”
After Portuguese language study, Tim & Roxanne moved to Boa Vista, Brazil, to serve as a pilot/mechanic family. They were also able to fly in Mozambique, Africa, for a time to help cover another Portuguese-speaking program. They returned to Santarém, Brazil, then moved to Manaus for the second half of their term.
In Santarém and Manaus, Tim continued a seaplane ministry to aid local churches and various missions in church-planting, giving wings to the Great Commission. In order to expand the Gospel outreach to more than 30,000 isolated communities along the Amazon River, Tim ferried a Cessna 206 amphibian from Coshocton, Ohio, to Manaus, Brazil. He shares, “The people we fly for are our heroes, and we are so glad to be able to help them in every way we can.”
Tim grew up in San Diego, California, where he accepted Christ as his Savior as a young child. At the Lutheran Bible Institute in Seattle, now Trinity Lutheran College (TLC), his heart was touched by the Lord, sparking the desire for full-time Christian service in mission aviation. Tim attended Christian Heritage College in southern California, where he studied Mission Aviation Technology. He holds commercial and instructor pilot licenses with instrument, landplane, and seaplane ratings, and airframe and powerplant mechanic licenses.
In addition to 18 years of home-schooling, Roxanne’s days were filled with flight-following, hospitality, discipling women, helping with children’s ministry, and translating for work teams and short-term missionaries. Roxanne grew up in a Christian home in Seattle, Washington, and later met Tim at the Lutheran Bible Institute. Following their marriage, Roxanne trained as a licensed practical nurse.
Roxanne’s favorite verses come from Ephesians. “But God…rich in mercy, made us alive in Christ even when we were dead in transgressions…For it is by grace you have been saved by faith…for we are God’s workmanship, created in Jesus Christ to do good works, which God prepared…for us.” (Eph. 2:4-5, 8-10) Roxanne shares, “Our time on earth is for knowing this and sharing it with others.”
Tim and Roxanne moved to the Seattle area to work remotely with a primary responsibility of maintaining the currency of MAF’s technical publications library. Tim feels truly blessed to continue to play a vital role in the ministry of MAF in this area which is critical to the safety of our flight operations around the world. Roxanne went home to be with the Lord in the fall of 2020. Tim has now moved to Texas and continues to work remotely with MAF.
The Aults have 4 adult children – Amber, married to Aaron; Corrie, married to Carlos; Ben and Caleb.
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 Tim’s ministry. Please prayerfully consider becoming a Ministry Partner with him through prayer and/or financial support.
The U.S. offices of MAF serve as a hub for MAF services worldwide. A day in the life here includes specialized flight training, staff mobilization and counseling, purchasing and shipping of aircraft parts, finance and accounting, administration of an Internet gateway for worldwide email, fund raising, printing and mailing of various materials, and many, many more activities. Some staff serve around the country; training future pilots and mobilizing potential candidates to serve with MAF.
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 in the exercise of its mission and care of its staff.
