Change Happens When People Pray

Join our prayer Team

Intercessors wanted!  A great body of intercessors is needed to make any lasting change in urban poor communities.  Factors which hold people in poverty – corruption, spiritual oppression, systemic political and economic injustice, crime and violence – are not easily changed or corrected.  It takes a movement of God to break strongholds and we’ve seen it happen through the faithful, fervent prayers of individuals and groups.

Sign up to receive our prayer newsletter which only goes out to our intercessors and commit to pray at least twice a week for us. Share it with others in your community or church. Host a prayer vigil or a time of focused prayer and fasting.  

“One of the most convincing arguments for the existence of our great God is to see how lives and circumstances change in His name and how people have the power and wisdom to do such great work . . . receiving your [prayer] bulletin and praying is a great blessing for me.”  -R.K.

Invite us to speak in your area

With many years of experience at the front-lines of urban ministry, cross-cultural engagement and combating poverty and corruption, our leaders have gained valuable insights on the intersection of theology, missions, church growth, emotionally healthy spirituality, social change, economic development, engaging the powers, strategic leadership and city transformation. Request one of our dynamic speakers to speak at a conference, public event or lead a workshop or retreat in your community or church. You can be the one to spark great change by having the Urban Mosaic message shared in your area!

“Looking at the problems that faced the people and children in Mexico City I felt quite desperate, but after Jean-Luc’s sermon, I felt hopeful, encouraged!  His passion and commitment to Urban Mosaic is inspiring and stirred something in me to want to do more, be more, and to serve more.”   - K.B.
"Going through the "God's Transforming Story" completely changed my perspective on the Bible, its message for today, the church's role and my own calling as a follower of Jesus. It re-energized my faith, re-ignited my passion, and compelled me to play my part in the Story of God with his world." - CR
"Learning about poverty and city transformation completely re-shaped my understanding of mission. Connecting my own spiritual poverty and lost-ness to the poverty and lost-ness of many urban dwellers made me realize that evangelism goes far beyond bringing individuals to Jesus, but includes changing systems and structures that mar the image of God in the "other"."  - SS

Volunteer : From Near or Far

Be the “hands and feet” that help bring about change in people’s lives and communities.  Here are some practical ways to put your passion and skills to work as a volunteer:



Visiting teams have helped remodel schools, build ecological latrines and break ground on a life-giving retreat and training center for Christian leaders and pastors.  Donated skills and materials pair up wonderfully with the willing hands and hearts of community members.

“The very best part of our experience was working alongside Mexican and building relationships through fellowship . . . I go to help others, but without fail end up being a recipient of the blessings we find in service.”  J.H.


Medical campaigns form a vital part of our strategic health interventions in slum communities.  Professionals and general volunteers alike help provide care and gather baseline information crucial to planning follow up care on both and individual and community-wide basis.  Many new families are drawn to participate because of the newly available services, notably deepening our reach into the community. 

“We are doing much more than putting a Band-Aid on a wound.  With the help of ProSalud and the trained counselors . . . our patients for a day have follow up either with the local clinic or for social services . . .  the gratitude of the Mexican community is immense!”  J.R.

Kids' Camp

Community children and youth are drawn in great numbers each summer for fun and learning led by program staff and  visiting volunteers.  Whether telling Bible stories, teaching arts and crafts, singing songs or joining youth in sports-focused day camps, volunteers help magnify the care given to each child.

“I loved seeing the kids and their families . . . seeing their excitement for the program grow each day was awesome!  I was sad to leave but it felt good to know the impact we were able to have . . . in such a short time together.  I am looking forward to coming back!”  A.B.
