Local Ministry Stories

By: Reality SF

In this blog, we will regularly add profiles of our Local Missionaries and Local Ministry Partners, whom we offer partial financial support through Local Ministry.

Jason & Justine Martinez
YWAM San Francisco & Because Justice Matters


What do you two currently do as missionaries?
Jason is the Director of Operations at YWAM San Francisco, overseeing finances, facilities, and office management of the YWAM’s Tenderloin Center. He is also on the leadership council for the ministry. Justine is the HR Director at Because Justice Matters, supporting all of the BJM staff through systems as well as pastoral care. She is also on BJM’s Executive Team.

What do you love about this work?
We love the lens that we’ve been given as missionaries in San Francisco — the way it helps us dig deeply into loving the city in tangible ways. Loving a city brings pain and sacrifice as well as joy and delight. Grieving losses, celebrating miracles, and holding on to the hope and vision of God’s plans for San Francisco has been a process that has enriched our personal faith journeys in more ways than we can count!

Describe something God has shown you during your time serving.
God has shown us unending faithfulness in our financial needs as a family. Some seasons are paycheck to paycheck; in other seasons there has been more than enough to give back. Throughout, we have certainly witnessed His provision in thousands of ways both subtle and extravagant.

What have been some of your most memorable experiences? 
All of our most memorable experiences as missionaries have had to do with listening to the amazing stories of others and witnessing God speaking directly into those stories. We are extremely honored to have been able to witness God speaking to beautiful humans in Italy, Morocco, Turkey, Thailand, Vietnam, as well as on the streets of our own Tenderloin. It’s been a precious and transformative adventure for us as a family over the past 13 years.

Udom Setthaya Missionary

What you do in your current ministry?

I am full-time volunteer staff with RI (Restoration Initiatives) of YWAM San Francisco, which helps to restore, empower, and serve our friends on the streets of the Tenderloin.

What do you love about serving as a missionary?

I love how God uses me in different ways. It is very challenging, and often I don’t know what it’s going to be like! But this ministry leads me to learn how to trust and have faith in God, to be patient, and  to lean on Him when I face difficult circumstances. And I love how God uses my ability to serve and impact others!

Describe something God has shown you during your time serving as a missionary.

God has shown me so much: how to love and care for anyone in my life (family, friends, colleagues, strangers, etc.) even through small acts of giving. It can make a big difference, just as Jesus says in Mark 12:30-31.

What has been your most memorable experience serving as a missionary?

One of my most memorable experiences is having my family in Christ with me everywhere I go. This is a privilege from God. I am so thankful to Him that I have my church and friends — my brothers and sisters — supporting and walking with me on the mission that God has for me. No matter what I have been through, I do know that my family is praying for me.

Brooke & Karen Butler
Athletes in Action, UC Berkeley


What you do in your current ministry? 

My wife, Karen, and I lead the Athletes in Action staff team and ministry at UC Berkeley. We are involved in winning athletes to Christ, building them up in their faith, training them in how to multiply their lives and sending them to reach their teammates and multiple areas of society after graduation. We also build relationships with and minister to various coaches and athletic personnel.

What do you love about serving as missionaries?
We absolutely love seeing students won to Christ and experiencing redemption and healing! Seeing these students become world-changers who impact their teams and friends is so life-giving!

Describe something God has shown you during your time serving as missionaries.
We served at Stanford for 9 years, Croatia and Bosnia for 21 years, and now at Cal for 4 years. In each of these chapters, we have been shaped and our self-confidence has been chipped away at — so we have learned in much deeper ways what it means to find our confidence in God. Karen and I have become acutely aware that God is always at work and that we are simply being led in to joining Him in His work and plan.

What has been your most memorable experience serving as a missionary?
Probably the most memorable experience was handing over the reigns as Country Director for CRU in Croatia and Bosnia to a Croatian National staff. We set out to work ourselves out of a job and see Croatian leaders raised up to take on the leadership of CRU. And after 21 years of labor and prayer, God fulfilled that calling!
