Pastor John Ortberg reflects:

Conforming to boundary markers too often substitutes for authentic transformation.

The church I grew up in had its boundary markers. A prideful or resentful pastor could have kept his job, but if ever the pastor was caught smoking a cigarette, he would've been fired. Not because anyone in the church actually thought smoking a worse sin than pride or resentment, but because smoking defined who was in our subculture and who wasn't—it was a boundary marker.

As I was growing up, having a "quiet time" became a boundary marker, a measure of spiritual growth. If someone had asked me about my spiritual life, I would immediately think, Have I been having regular and lengthy quiet time? My initial thought was not, Am I growing more loving toward God and toward people?

Boundary markers change from culture to culture, but the dynamic remains the same. If people do not experience authentic transformation, then their faith will deteriorate into a search for the boundary markers that masquerade as evidence of a changed life.
