YES! You can do a Missions center! In fact, if you'll look at your Director's Planning Pack, you'll see that Folder B contains NEW missionary object talks, an article about missions and service projects and also a whole set of missions-related activities! All of these can be used either to create a separate Missions center or can be used as part of activities related to your church's missions project.
And if you are looking for a missions project, Gospel Light supports onemillionchildren.org. In fact, every time you buy a Gospel Light product, you are supporting the project! But VBS kids often support it as their project, too!
