Kilian grew up in the Evangelical-Lutheran Church in the German countryside, hearing about faith his entire childhood. At the age of 12, he discovered the heart of the gospel and God's love at a camp, desiring to follow Jesus since then. After years of serving at camps and being discipled, Kilian explored his heart for mission during internships in Manchester and Chemnitz at the age of 19, leaving him with the desire to reach people for the sake of the gospel. In 2020, he started studying Theology, Mission, and Ministry with ForMission College in partnership with a missional organization and his local church in Germany. Studying the depths of God and his word, Kilian focused on missional leadership in his dissertation, proposing new ways to combine leadership styles in ministry. After finishing his Bachelor's degree in 2023, Kilian took on the role of an academic administrator on the Higher Education team for Josiah Venture. In this role, he supports students and staff of ForMission College in order to enhance their college experience. His goal is to develop existing processes, as well as paving the way for new experiences, equipping Christian leaders in Central and Eastern Europe for effective missional ministry.
