In 1983, for Palm Sunday, John Piper preached a sermon on Matthew 21:33-46. His sermon was basically a parable, following and unpacking the storyline of Jesus' parable. I read it years ago and it hit me like a freight train!
I was reminded of it yesterday and I re-read it. I was overwhelmed again. I plan to read it to our family on Christmas Eve. Perhaps you'll want to incorporate it into your personal or family reading this Christmas.
You can listen to it or read it here.
