Now, don't get me wrong: I'm not rubbishing penal substitution. But there are other options that have been advocated by Reformed thinkers of the past.

I don't really have a lot of interns, although I do now use Research Assistants to help me compile indexes when that is necessary.

We are still living with the consequences of that today in popular Reformed thinking from the likes of John Piper, R. C. Sproul, and Tim Keller.

God shows us in Christ what he would have to do if he were to punish us for our sins.

For those who have only ever read about [John] Calvin, reading the man himself is an invigorating experience.

I recommend Doug Sweeney's recent book [Jonathan] Edwards the Exegete (Oxford University Press, 2015), which is a terrific treatment of the way in which Edwards was steeped in the Bible, so that it shaped the whole of his thinking.

The book [Saving Calvinism] itself is not recommending that we move the borders, so to speak. It is recommending that we look at what lies within the confessional bounds of Reformed thought.
