It was because he [Calvin] saw God’s law as the means to moral improvement and to a healthy church that Calvin chose to preach 200 sermons on the book of Deuteronomy.
My two cents
Wow, I wish I could have been there in the 16th century to get the lowdown on Deuteronomy. That was when 2 Timothy 3:16 was taken seriously by Bible believers. Fast-forward to the present-day, and I think in most churches you’d be hard-pressed to get anywhere near that number of sermons from your local pastor.
Sometimes I wonder if there is a pastor who secretly would like to preach much more from the book of Deuteronomy, but he’d be chased out of town by his congregation. That’s a damning commentary on today’s believers, especially when I’m told that Deuteronomy was the book that Jesus quoted from the most. People of my generation miss out on that old school approach, and it shouldn’t have to be that way.
