Ok lots to say here but before I take the time I have resources for everyone that are....preparatory to that discussion! I really feel this is something God is giving me as a mission. To spread news about the endless joy available even in the darkest of times through delighting in Christ.
So some links to prepare you from the prophet of joy John Piper:
The Quest for Joy - a series on this topic that is unparalleled!

but for the nutshell version go here:
The Supremacy of Christ and Joy in a Postmodern world
this was a message given at a big conference and sums this whole theme up in a marvelous way

I want to take a lot of time and prayer and thinking before I release anything incomplete about joy. So be patient but it will be coming soon.
