In these sermons we see that the truths experessed by the Apostle Paul are not only a fitting conclusion to Romans 9-11, and indeed to the preceding chapters as well, but are also an interpretative key to the past and the future.

The eleventh chapter of Paul's Epistle to the Romans is one of the great and notable chapters in the whole of the Bible. I know that I have a tendency to say that about every chapter which we consider, but there are certain chapter which stand out as one reads through the Bible.
