Serge means "joining together rough edges to form a smooth seam." Serge (formerly World Harvest Mission) is a ministry that sees God weaving together the ragged parts of a fallen world with God's goodness, making the tattered beautiful. This grace compels God's people to go, to join their lives with the communities Serge serves around the world, as Christ makes all things new. This is grace at the fray. Serge's work consists of sending and caring for missionaries, discipling people around the world, and developing--such as Sonship and The Gospel-Centered Life--for spiritual growth. Serge started as an extension of the missions outreach of New Life Presbyterian Church in Glenside, Pennsylvania. Jack Miller--the church's founding pastor, as well as an author and evangelist--brought local and regional church leaders together to serve in global ministry. After many informal missions trips to Ireland and Uganda, Serge was officially established in 1983.

Today, Serge has more than 200 missionaries serving in 16 countries. It was while doing cross-cultural, team-oriented ministry that Serge discovered how challenging it is to be grounded in a biblical identity as sons and daughters of God--even in the midst of missional work. So Serge leaders began developing teaching materials to show how the realities of the gospel apply to our lives, work and relationships. Serge's ongoing vision is to plant and equip churches that are empowered by grace for the world's good and God's glory. Serge believes the motive and power for mission is the gospel of grace at work in the life of a believer, and this message is clear in each of their gospel-centered Christian books and small group discipleship, missional ministry, and biblical counseling.
