The audio and manuscript (and now video) are posted of John Piper's lecture last night at the Evangelical Theological Society in San Diego. Here is John Piper's closing plea:

For the sake of the undiminished fullness of the glory of Christ and for the sake of the radical sacrificial love that the world needs from us, I plead for your allegiance to a robust, biblical, historic vision of Christ whose obedience is counted as ours through faith alone.
