Duarte – The Secret Structure of Great Talks is a good listen for all preachers.

This is Nancy Duarte’s TEDS speech (18 minutes) about Great Talks. Although there is nothing really “Christian” about this video, it has made a big impact on me. While I watch this video I realized that a lot of the things she is saying is just good preaching. It parallels biblical preaching, i.e. present the need (sinner is under the condemnation of God), present the end result (sinner saved, living in Christ), and then present the bridge between the two, i.e. how do we get from the first point to the conclusion. Excellent speech!
