Rather than looking to Keller's work for the discussion I've been leading monthly, this time I want to discuss a recent article from Relevant Magazine: Your Job is More Important Than You Think.
I look at Relevant from time to time; I appreciate the perspective from 20-30 something Christians.
I suspect our discussion will go along the lines of "how do we as a church validate calling in the 20-30 somethings in our midst?"
