The Book of Isaiah... chapters 1 through 12
A video was shown during the sermon 'Wayward Children' at the 11:37 mark. If you want to watch the same video, so the sermon will make more sense, then watch 'Killing Kryptonite...Justin and Angela' on Youtube.com.
The last sermon on Isaiah 12:4-6, in this section, has a few breaks that include a song (7:50), a testimony (9:13), more songs (14:01) and a prayer focus (16:25). Understanding that will help with the seemingly disjointed message.
