The Institute of East Asia Training Extension is a ministry sharing the gospel with communities across Indonesia. Working closely with the Seventh-day Adventist Church organization, it established the first Seventh-day Adventist International Church in Bandung and reaches people from island to island through various forms of outreach.

Its literature ministry translates Spirit of Prophecy books, designs and prepares them for printing, and brings them into communities through direct book sales. iEAT.ex has also supported several young people through university at Adventist institutions, helping them complete their education.

Through these ministries, several people have come to know the Lord and committed their lives to Him through baptism.

The iEAT program, with Eugene and Heidi Prewitt, is listed as a separate project.
