Here is a scripture chain that gives you some ideas you could use on a talk about the Christian Courage. This chain was inspired by Elder Robert D. Hales talk from October 2008 General Conference. It is not intended to be inclusive, but will give you some ideas that could start you in a good direction. Please comment on any topics you would liked to see added and check back for additional talk topics.

1 Nephi 8:33
Alma 14:14-29 (Notice how long Alma and Amulek suffered before doing anything.
