Timothy Keller’s newest book releases tomorrow — Every Good Endeavor: Connecting Your Work to God’s Work. It’s a clear and thoughtful treatment of vocation and calling.

We put Dr. Keller on the line to ask him about the 9 to 5 labors into which we invest so much of our lives. So what is the purpose of our work? What if we get stuck in a job we don’t enjoy? And why does it seem the church has such a hard time getting its arms around vocation in the first place?
