ACBM activities
Work began 1969. While fieldworkers continue to work and travel safely in Indonesia, caution needs to be exercised due to the dominance of Islam and occasional terrorist activity in large urban centres. Main fieldworker visits are in June-July to coincide with the annual Study Week.
In the capital city of Jakarta, a tiny but dedicated ecclesia shines God’s light clearly at its regular meetings. If you are visiting they would love to hear from you.
Solo Ecclesia, in Central Java, is a much larger ecclesia and conducts a full range of activities, including Sunday School, youth events, and a sisters’ class. Attendance at the sisters’ class is excellent and is a great support particularly for the widows and single sisters in the group.
