When your download is complete, the files will be saved in the Files app on your device.
From the Files app, find the zipped folder titled "The Body of Christ.zip" and select it. This will unzip the contents and create a new folder titled "The Body of Christ".
Once the contents have been unzipped, select the newly created folder and both the audio files and corresponding study notes will be there.
For the best experience, it is recommended that you either print the study notes or view them on a separate device.
