In case you are unaware, T4G is going on right now. This is one of the best conferences that I think you could hope to plan to attend (I have been there in the past and so I speak from experience). I am one of the many who wish they could be there. T4G is a conference primarily for pastors and church leaders though they encourage pastors to bring some of their men.
Here is one of the many excellent sessions from this week (it is over an hour long so clear out some time to watch and listen). This sermon entitled Divine Sovereignty: The Fuel of Death-Defying Missions was delivered by pastor and author David Platt.
In case you would like some notes to follow along, Aaron Armstrong (who is attending) has done us the courtesy of giving us his notes from the sessions.
