Annual conferences, missionary training schools, and specialized programs designed to equip and connect the BIO missionary family from around the world.
BIO hosts several recurring events each year — bringing together new candidates, veteran missionaries, supporting churches, and ministry specialists for training, fellowship, and encouragement in world evangelism.
The Conference on World Evangelism gathers missionaries, supporting pastors, and church members for a week of missions preaching, field reports, and fellowship. This is BIO’s flagship annual gathering — a highlight of the year for the entire BIO family.
