Global Missions

Global Missions We desire to implement our vision globally by working to support missionaries in an international effort to engage people with the gospel.  Our primary sending agency is Mission to the World, the official mission organization of the PCA, however we do support various other missionaries as well. Listed below are the global ministries and missionaries we support. 

Rev. Tom & Ann Austin

Ash & Betsy Aeschiliman

MTW / Medical Missions: Latin America

With a BSN-RN degree, Betsy ministered in pediatrics for 38 years before joining MTW as a medical missionary. Betsy has a heart for mercy missions that combines her nursing skills with a passion to share the love of Jesus in a hurting, lost world.

Betsy assists church planters and national pastors by bringing short-term medical teams to encourage them in their callings. Betsy prepares and prayerfully guides five teams annually to help meet this number one request from our overseas colleagues.

Ash is an honorably retired teaching elder. He pastored Missouri and Illinois churches, worked for Covenant Seminary, and ministered through CEP (now Christian Discipleship Ministries). After their 2015 marriage, Ash was approved as an MTW missionary. They now joyfully serve together, both overseas and at missions conferences. Ephesians 3:20-21 is a pillar for their life together.

Using a mobile-clinic model based on Matthew 9:35-37, they minister compassionate care with prayer and evangelism. Ash and Betsy are active in recruiting healthcare professionals and non-medical volunteers for teams. Betsy also trains medical mission leaders.                                                                                                              

Ash and Betsy invite you to co-labor with them through prayer and financial support for the glory of Christ and the hope of nations. They also invite you to consider joining one of their medical teams!

Bo and Brynne Lancaster 

MTW / Rotterdam, Holland

Bo and Brynne Lancaster are excited to join a team of Dutch church planters in the thriving city of Rotterdam, Holland. Rotterdam is one of the most multi-cultural cities in the world with over 170 nationalities representing nearly 50 percent of the population. It is this multi-cultural population that Bo and Brynne will be working with, with their daily lives revolving around engaging the people of Rotterdam by meeting them where they are and living life with them, so as to show and share the truths of the gospel. They will be building communities of English-speaking people that will feed into an existing church plant, with the hope that these communities can eventually form their very own church.

The Lancasters will also be working in a local refugee camp, teaching and discipling a small group of believers there so that these believers will be able to share the gospel in their own languages with others in their camp.

Lastly they will be assisting a student ministry at a large university in Rotterdam. This university has nearly 8,000 international students from all over the world. Bo and Brynne’s prayer is that many of these students would come to know Jesus and then be trained and discipled in the church so that when they return to their home countries they can build the Church there.

  Children: Marin and Willa.  Contact:

Impacto / Evangelism: Guatemala – Pastor Luis F. Martinez is a native of Guatemala and leads crusades in the United States and in Spanish-speaking countries around the world.

Rev. Keith & Ruth Powlison

MTW / Church Planting: Peru

Keith and Ruth met at Columbia Bible College in 1977 and married in 1978. They have four children and five grandchildren. The Powlisons began serving on the foreign mission field in 1984 and are currently serving in Cusco, Peru. They serve with a team of several families in a combination of leadership training, church planting, clinic ministry, and the Josephine House orphanage.
Ruth founded the Josephine House, a home for abandoned and abused children, in 2008. Approximately 35 children have been rescued from abusive and life-threatening situations by this ministry since its inception. Ellie and Emma, both Quechua, joined the Powlison family through adoption. Seeing the family situations that the girls came out of made it even more clear to Keith and Ruth that there was a vital need in Cusco for a ministry to children at risk. The Powlisons realized they couldn’t adopt every child in danger, but they could create a safe place for many through the Josephine House.

Please pray for the Powlisons as they enter into many challenging areas to train and establish national workers in and around Cusco. Contact them at about ministry possibilities, medical teams, construction teams, or other short-term opportunities.
