A Christian university connected to the Evangelical Free Church of America is Trinity International University (TIU). Illinois and California are home to TIU campuses. All of these institutions have the goal of "educating men and women to engage in God's redemptive work in the world," even though each one has a different function and offers a different experience. Since their students are entrusted with the gospel to think and live as Christ-followers in the twenty-first century, they wish to equip them to lead others across all entities and disciplines.
