John Piper is a well-known 77-year old Minnesota pastor and media presence with four sons, three of whom currently do not rock his spiritual boat. Barnabas is a pastor in Nashville, Benjamin a construction worker and Karsten a college English teacher. If either of the latter two are not believers in good standing at their local churches, we certainly never hear about it.
Yay for good parenting doing what it is supposed to do.
Abraham Piper is another story. The man even has his own Wikipedia entry and a TikTok following of over two million for his two pages, self-described as “a smidge of sacrilege” and peppered with salty language. Not a believer, and not only out and proud of it, but formally excommunicated to boot, and dedicated to taking shots at the faith and publicly mocking his father’s beliefs.
