One of the simplest and most consistently effective pastoral tactics in Hendricks’s case studies: track who’s been absent for 2–3 weeks, send a warm personal note (not a form letter), follow up with a personal visit or call. Most return the following week.

Low-tech. High-touch. It works because absence rarely means “I’ve decided to leave.” It usually means “something got in the way and I wasn’t sure if anyone noticed.”

The personal contact does two things: it communicates that the person was noticed (belonging is real, not incidental) and it removes the social awkwardness of re-entering after a gap (someone has extended a bridge back in).

This is in contrast to programmatic retention strategies — membership classes, re-engagement events, follow-up emails. Those address the institutional relationship. The personal visit addresses the human one.

The principle generalizes: people stay where they’re genuinely known, and leave where they’re not. The note and visit are just the mechanism for communicating “you’re genuinely known here.”

Practically: this requires someone to own the tracking and the follow-up. Not automated — personal. The moment it becomes a system, it loses the quality that makes it work.
