Calvin doesn’t explain it nearly as well as Jesus does in Matt 25, or He does in Rev 20, or in a whole bunch of Gospel and NT passages. Once again, we have the theology of Paul admonishing his renegade churches replacing the message of Jesus.
As a matter of fact, Calvin omits these passages from his theology entirely. I’m surprised that they survived as Scriptural after Luther took his machete to the Bible.
Ah Luther, the man of ‘ohne’ and ‘allein’ ... but God Saved him anyway.
