Thanksgiving day presentations

This year, we were able to have some slideshows of a lot of things to consider.  My Dad presented on his year in Ethiopia, giving service and love.  My Uncle Son also brought some slides.  He talked about growing up in Vietnam, the first branches of the church out there, and most especially escaping from Vietnam before it was taken over by Communists.  His brother in law wrote a book about it called When Faith Endures.  How do you teach that to your children without experiencing it?
