This past April I live-blogged the plenary sessions of the Children Desiring God conference:
Session I – John Piper
Session II – Wayne Grudem
Session III – Wayne Grudem
Session IV – C.J. Mahaney
Session V – David Michel
And posted photos (I and II and III).
Now Desiring God has made all of the audio from the 2005 and 2007 Conferences freely available–including the elective seminars. They also made available several short videos from David Michael, Sally Michael, and John Piper introducing their mission and vision.
