What resources do you suggest for a spiritual gift class?

http://buildingchurch.net/g2s.htm offers a free online survey, ala C. Peter Wagner. I don't know of any video curriculum though. Godspeed.

Faith Alive has a program we have used, called Discover Your Gifts. Here's a link to the student guide: http://www.faithaliveresources.org/Discover-Your-Gifts-Student-Book There's also a teacher guide and a version intended for young people.

I haven't seen any video materials.

Are you planning to use the material with new Christians, young people, a mixture etc? We found the material interesting but perhaps best suited to those who are new to the concept of spiritual gifts. There is more in-depth material available, but this is a great "survey" course.
