Don’t pray because it is about disability or suffering – it isn’t. It is on Calvin and you can follow it here.
Pray because people who get saturated in God-honoring, Christ-exalting, prayfully-dependent teaching and preaching that, Lord willing, is happening at the conference deal with the issue of disability and suffering in much more helpful ways.
And if you’d like to hear some good teaching on suffering, the 2005 Desiring God National Conference, Suffering and the Sovereignty of God, is very good. It includes a wonderful message from Joni Eareckson Tada I recommend.
Thank you for praying!
The Works of God 
Actually yesterday turned out to be a lot about suffering. Maybe that’s the way it is with the real gospel. The topic may not be “suffering” but it’s there.
