The 3 AGL is an interdenominational mission organization rooted in Bible-centered gospel truth and Reformed theological conviction. Located in the tri-border region of Brazil, Colombia, and Peru in the Amazon rainforest, it exists to train and equip national church leaders through the Tri-Border Theological Seminary and the Amazon Tri-Border Evangelical Church. These leaders are prepared not only to proclaim the gospel and plant healthy, reproducing churches, but also to guide those churches toward complete spiritual, ministerial, governance, and economic self-sufficiency. By establishing indigenous congregations that are fully autonomous—dependent on Christ alone, governed by their own biblically qualified elders, and financially sustained through the faithful giving of their members—3 AGL enables the churches of the Amazon to fulfill the Great Commission in their region and beyond, advancing world evangelization for the glory of God alone.
