I have always considered the lyrics “Whatever gets you through the night, it’s all right. It’s all right.” to be a bit of a personal motto when it comes to reminding myself that it is ok that other people don’t believe the same things as I do. It is a message of not just tolerance, but of acceptance. That it really is alright is a powerful thing to remember.
Finally, as pretty much everyone knows, his song “Imagine” is the finest statement of Humanist beliefs ever put to music. John - you are missed but not forgotten.
