I was just wondering if at some point, Logos offered a collection of Mark Driscoll's sermons.
Yes they did.
I wonder why they don't offer them any more. The quality and value of his sermons did not change because he resigned.
I don't know. Probably Faithlife was told to remove them. If you search around you can find people who purchased them when they were available and you might find someone willing to sell them to you.
They probably ran them through a plagiarism checker. That didn't change when he resigned, either.
But don't worry, with the evangelical rock-star industrial complex in place, he'll be back; probably sooner than later.
