Sam and Sarah grew up on opposite coasts of the United States but were brought together through their undergraduate studies at The Master’s University. Knowing they shared a mutual desire to devote their lives to foreign missionary work, Sam and Sarah were married in August 2013. After their wedding, Sam began serving on staff at Crossway Church in Keene, New Hampshire. Their firm conviction about the centrality of the local church prompted them to spend several years ministering at Crossway. They wanted to serve faithfully and be affirmed in their call and giftedness for missions. These years were invaluable for fostering a firmly rooted partnership with Crossway Church that would remain steadfast throughout their lives of missionary service. The Wullbrandts have two children—Cooper (2014) and Wren (2016).
In 1998, a team of three missionary families was sent out from Grace Community Church. They were invited by a Christian Croatian national named Misko Horvatek who saw Croatia’s dire need for the gospel. In response to Misko’s plea for help, the team of three families set out with the vision and call to do the work of church-planting, church-strengthening, and leadership development in Croatia. Providentially, due to the similar language of the six countries that comprise the former Yugoslavia, their ministry extends beyond Croatia and includes Slovenia, Bosnia, Serbia, Macedonia, and Monte Negro (a combined population of over twenty-three million souls).
As members of the GMI Croatia team, the Wullbrandts will continue to build on the foundation that has been laid through leadership training, church-planting, and discipleship in Croatia and throughout former Yugoslavia. Sam will train pastors in the skill of expository preaching and shepherding, serving as a professor at Theological Biblical Academy—a seminary in Krapina, Croatia that is part of The Master's Academy International fellowship of seminary schools (affiliated with The Master's Seminary). The life-giving gospel and the baton of gospel ministry must be “entrust[ed] to faithful men who will be able to teach others also” (2 Timothy 2:2). The Wullbrandts prize the privilege of involvement in local church ministry, operating under the firm conviction that God’s plan is for local churches to “equip the saints for the work of ministry” (Ephesians 4:12).
