Member Spotlight: Britt and Sherry Miller, Keystone World Outreach

By Anna Moore  ·  Apr 21, 2025

Britt and Sherry Miller of Pennsylvania are in their second decade of building the Kingdom of God—spiritually and physically.

“We never know where we’ll be next and what we’ll be doing next,” Britt said. “I just got back from Peru building a church and I’m headed to Mexico soon to put in a septic system for a church. We go where the Lord leads, to do what we can to share the Gospel.”

Ministry focus

The Millers have been married 38 years and have two daughters and three grandchildren. They don’t focus on humanitarian work but rather serving local churches and communities by constructing or enhancing safe places to learn and worship the Lord. They have helped to build churches, a college, and a Christian orphanage, and have shared the Gospel of Jesus Christ across the world in the process.

Their construction and outreach ministry, Keystone Outreach, isn’t dependent on a church or parent ministry but solely on the Lord’s provision.

Serving overseas

Britt and Sherry experienced their first mission trip outside the U.S. in 2004. Neither had ever been out of the country at that point, so they were a little apprehensive.

“We were diehard Americans, born and raised on American soil,” Britt said. “There’s enough need here that we never felt any compulsion to leave our own country borders. But in 2004, the opportunity came up to go to Mexico City and we both, separately, felt compelled to go.”

On that trip, the Millers did masonry, plumbing, and electrical work at a Christian college. They felt right at home and knew this was the type of ministry the Lord wanted them to focus on.

The couple continued serving on short-term mission trips throughout South America over the next four years and experienced their first solo trip in 2008. There was an urgent need in Pallatanga, Ecuador, where a ministry conference was planned for about 5,000 people. The problem was there were only two restrooms.

“They needed help immediately,” Britt said. “Within two weeks we were there to assist in providing 10 bathrooms. That was our call from the Lord.”

Traveling on mission

In 2016 the Millers decided it was time to start their own ministry rather than working through other ministries for their mission trips, affording them more flexibility and management of their projects. Since creating Keystone Outreach, they have traveled to 16 different countries, including the U.S. and Canada.

“We felt from the very beginning of the Lord’s call that this was what we could do to enhance and build the Kingdom of Heaven and win the salvation of souls,” Britt said. “Frequently a big part of it is encouraging the saints as well. Sometimes we may visit churches or ministries not to speak or preach, but just to encourage the leadership there, and they need that.”

The couple sold their modular housing business in 2022 and went into full-time ministry while becoming retired from the marketplace.

“I think ever since we’ve been married, we looked forward to retiring and traveling,” Britt said. “Never did I think it would be for missionary work, though. I thought it would be leisure travel. But we love it.”

Working ‘right up our alley’

Britt grew up around construction work and Sherry has experience working on the business side.

“I’ve been in the deepest ditch and on the highest roof and done everything in between,” he said. “So when there’s a job that needs construction, it’s just right up our alley.”

From plumbing and wiring to masonry, roofing, drywall, window installation, and more, the Millers are willing to do whatever is needed. Britt will take a few tools that are special to him, and the rest of the materials or any equipment needed are obtained locally.

Sometimes it’s just the two of them, and other times they lead a team of volunteers. While Britt focuses mostly on the trade work, Sherry helps with support and logistics, ensuring all are fed and have places and time for rest.

Enriching the Kingdom

Before leaving on a mission trip, the Millers search for a local fellowship that is biblically based where they’re going so they have someone they can meet up with and so that anyone who professes salvation while they are there has a place they can be supported while on their journey.

“We always make sure there’s a place for them to go,” Britt said. “The church I recently helped with in Peru was a strong, biblically based church, and on the opening night, there were 192 people there to hear the Gospel preached from the pastor. So, we trust that that will enrich the Kingdom of Heaven.”

When they meet people on the streets in their destinations, they hear many different life stories and often hand out their unique poker chip or dish cloth Gospel tracts.

“It may just be one soul at a time, but we need to know we have a place to send them or encourage them to go for the support and growth they need in their walk with Christ,” Britt said.

The table is covered with items such as toothpaste, shampoo, shaving cream, and washcloths. A Walmart bag sits in front of her, ready to be filled with the sorted items. In the background there is a chalkboard with motivational words.

Lydia’s Grace

As a subsidiary of Keystone Outreach, Sherry manages a women’s ministry called Lydia’s Grace. The name is inspired by the faith of Lydia in Acts 16. Sherry collects and distributes women’s care packages to homeless shelters, women’s centers, rehab centers, Bible camps, and homes for women in crisis.

While working with the homeless population in Columbus, Ohio, Sherry was once tasked with getting some women’s personal hygiene products from a storage cabinet for a woman with an obvious need. What she discovered made an impact on her.

“It broke my heart because there wasn’t much there and I thought, ‘These are some of the most basic things women need,’” she said. “It’s not a want or desire, it’s a need, and I just felt prompted ever since then.”

She’s since been on a mission to get donations from churches to help provide for the need and travels “wherever we can drive our vehicle” to drop them off, including in Canada.

‘Give it a try’

The couple encourages anyone who has not served on a short-term mission trip outside of the U.S. to do so because it’s eye-opening.

“Go and give it a try, because it makes you really appreciate what you have more times than not,” Sherry said.

It’s also rewarding.

“If the Lord has me travel 3,000 miles for one soul, I’ll do it,” Britt said.
