TL;DR:
Each June, Nazarene churches participate in the World Mission Broadcast Offering that supports the Church of the Nazarene's radio, television, and internet evangelism worldwide. These programs reach places where missionaries cannot go, crossing barriers of language, distance, and politics to share the gospel. Congregations can promote this effort with downloadable bulletin inserts or creative mission bulletin boards.

Need missions bulletin board ideas? Let these examples inspire you.
Our local church uses legal-size paper (8 1/2 by 14 inches) for Sunday morning worship bulletins or folders. Those sheets are folded into three panels, each approximately 8 1/2 by 4 2/3 inches.
Using materials from the General Nazarene Missions International office, I've created a series of informational inserts about missions to fit into those bulletins. Select either image below to download its full-size bulletin insert as a PDF. These could also be used as missions posters or even as starting points for missions bulletin boards.
An offering for World Mission Broadcast (radio, television, and internet programming) is taken by Nazarene churches each June.
Here is a promotional bulletin board used at the Bethel Church of the Nazarene in Kutztown, Pennsylvania.
