I really appreciate John Piper, perhaps most of all because his material is so freely available online.
As a subscriber to Preaching Today, I recently received a Piper sermon called, “How to Kill Your Sin.” It’s an excellent exhortation toward holiness presented in a biblical and passionate manner. Although I paid for the sermon, as a subscriber to Preaching Today, you can listen to and read it for free.
I highly recommend it.
