Serving with a Heart for God’s Kingdom: Ambassadors We’re Learning from the Summer Part I

Editor’s Note: This summer, 14 young adult Ambassadors are serving in congregations and ministries across Mosaic Conference. This article highlights three of these Ambassadors, and in the coming weeks, you will be introduced to the other Ambassadors.   

This summer, George Chile, 19 years old, a participant in the Mosaic Mennonite Conference Ambassadors, is dedicating time to serve God and his congregation, LA (CA) Faith Chapel with a heart full of purpose and passion.

“I want to make an impact guiding youth and leading a movement for Jesus,” he shares. 

As an Ambassador, Chile is serving in various ministries within his congregation, including working in the congregation’s labor department with church equipment, and assisting at Samaritan home—a housing project for unhoused individuals. He is also stepping in wherever else he is needed, demonstrating flexibility and willingness to serve. 

One of the most meaningful lessons he’s learned this summer is the value of offering himself fully to God. “Time and energy are nothing compared to the love God has for you, and it is worth giving to God,” he reflects.

Through his dedication and heartfelt service, Chile is growing in faith but helping to bring the presence of the Kingdom of Heaven into every act of service. 

This summer, Marciella Shallomita, a 22-year-old recent college graduate, is serving God by walking alongside the youth of her congregation, Nations Worship Center (Philadelphia, PA). As an Ambassador, Shallomita is combining her organizational gifts and heart for ministry to make a lasting impact. 

“Being an Ambassador is a good way to help my church in behind-the-scenes ministry, along with the regular ministry that I’ve previously and will continue to help with,” she shared. 

As an Ambassador she will coordinate youth service projects and organize a youth retreat. She hopes to strengthen the spiritual and communal life of the church’s younger generation. 

Shallomita’s approach to leadership reflects the values of servant leadership and fellowship. “I will serve together with the youth to help the congregation and broader community. The youth will be able to understand the true meaning of a church as fellowship with others, as Jesus intended.” 

“So far, I’ve learned administrative work and communications—planning and coordinating with the youth, retreat center, and other leaders in the church,” she said. 

Shallomita asks the Mosaic community to join her in prayer for the youth she is walking with this summer: “Please pray that God will help them understand and build a personal relationship with Jesus. Through the service and fellowship they’ll participate in this summer, pray that they can be more on fire for God.” 

Hensley Ducasse, a 24-year-old participant in the Ambassador Program, is serving his congregation, Homestead (FL) Mennonite and community with compassion, leadership, and vision. 

“My passion for Jesus Christ motivated me to become an Ambassador,” Ducasse shared. 

One of his bold goals for the summer is to open a food bank in the local community, to provide nourishment to those in need and serve as an invitation to connect with the church and experience God’s love. Ducasse is also planning to host sporting and gaming events for children and young adults—creating spaces of fun, community, and spiritual growth. 

“I’ve learned how to lead by listening and how to lead by example,” he reflects.  

Ducasse extends an open invitation to the Mosaic community: “I am taking prayer requests from anyone in need.” 

Ambassadors Gather for First Meeting

Many of the Ambassadors who gathered on Zoom for the first formation meeting of the summer.

On June 5, the 2025 cohort of Mosaic Conference’s Ambassadors gathered for the first time to officially launch their summer journey of service and leadership. This program offers young adults (ages 18–24) practical ministry experience in their local communities, helping them grow in their calling and commitment to God’s Kingdom. 

Led by Javier Márquez and Danilo Sánchez, the meeting began with greetings and team introductions, followed by a time of prayer and mutual encouragement. The devotional, based on 1 Timothy 4:12, reminded participants that youth is not a limitation but a calling to be an example in word, love, faith, and action. The reflection encouraged Ambassadors to live out their service with integrity, sensitivity, and courage—trusting that even small acts can reveal God’s Kingdom. 

One of the most enriching parts of the gathering was a group dialogue, where the young adults shared their motivations, hopes, fears, and dreams for the summer. Hearing one another helped build connection, empathy, and the assurance that they are not alone on this journey. It was a meaningful time of vulnerability, hope, and shared vision. 

The meeting closed with a sending prayer, commissioning the group into a season of growth, service, and transformation. We encourage each Ambassador to give their best, trusting that God will guide and use them powerfully to impact their communities!

Ambassadors We’re Learning from This Summer

by Brendan Sagastume

Editor’s Note: This summer, nine young adult Ambassadors are serving in congregations and ministries across Mosaic Conference. This article highlights three of these Ambassadors, and in the coming weeks, you will be introduced to the other six Ambassadors. 

Brendan Sagastume, 19, is a member of Perkiomenville (PA) Mennonite. Through the Ambassador Program this summer, he is working with both Mosaic Conference and Perkiomenville. At Mosaic, he works with the communication team, especially on the website and social media. He has had the opportunity to visit and interview some of the other Ambassadors and travel to their worksites. At Perkiomenville, he works with the worship team, youth group, and on other administrative tasks.  

Sagastume has led worship on a few Sunday mornings at Perkiomenville and created the announcement and countdown loop to play at the beginning of services. The experience this summer as an Ambassador has helped him with public speaking, administrative skills, and confidence, all while worshiping the Lord.  

“Learning what happens behind the scenes administratively in different organizations has been one of my takeaways,” Sagastume reflects. “I’ve been invited to think more critically about different experiences in my life and engage in discussion.” 

The largest impact that the Ambassadors program has had in Sagastume’s life has been his willingness to try new things and be more outgoing. He is grateful for this opportunity to work and learn more about what goes on behind the scenes at Mosaic and at his congregation. 

Nicholas Wiyono, 19, is a member of Philadelphia Praise Center (PPC). Through the Ambassadors program he is serving with PPC’s summer peace camp, where he assisted with about 20 children.  

Wiyono built on his skills and experiences as a Sunday School leader and helper at PPC. Throughout the summer, he has grown in his leadership ability, public speaking, and ability to be outgoing.  

Growing up at PPC, he had previously seen some of the work that Mosaic does, but now is able to see it more firsthand. He has really enjoyed seeing how both PPC’s summer peace camp and the Ambassador program can help people to grow individually and as a group in all areas of life. He is grateful for all the support he has received and for the opportunity to grow.

Ei Ya, 18, is a member of Whitehall (PA) Mennonite. During his time in the Ambassador program this summer, he has created the slides for Sunday worship, helped to rebuild and maintain the church website, and provided upkeep with the church gardens at a community park. He also spends time at Ripple Community, Inc., a Conference-Related Ministry in nearby Allentown. 

One of the biggest impacts the Ambassadors program has had on Ya is an increase in his ability to be outgoing. He initially had fears about having to interact with many different people in this program, but he found that, “people are easy to connect with. Attempting to be inviting with a smile sure goes a long way.”  

Ya was invited to the Ambassadors program by his pastor and has been so thankful for the experience. He says that this summer has been filled with great people and fun. It has taught him many new skills that will serve him well as he starts college this fall.
