Sometimes, sermons are too long to fit into a 25-minute radio broadcast, so they must be edited into two parts for air-time purposes. You’ll hear the first half of the sermon in part one, and part two will begin with some of the material you heard in part one to establish context for people who may have not heard part one.
If you’d prefer to listen to a sermon in its entirety with no part-one or part-two breaks, you can click on the title next to the program image under “From the Sermon,” and it will take you to the full sermon.
