I love purpose statements. I love them because I really don’t like guessing about someone’s motivation. It’s an uncomfortable place to be in. If I’m reading something someone wrote or listing to someone give a talk, I don’t want to be left wondering why they wrote what they wrote or said the things they said. I think this is partly why I like John’s gospel so much.

As the apostle John was drawing his gospel to a close, he thought it would be a good idea to make clear why he wrote it in the first place—to remove the mystery, if there was any.
