The 1980s were marked by optimism, technological progress, and memorable music, yet the era also witnessed tragic events. One of those tragedies, the Chernobyl nuclear plant meltdown, serves as a lasting example of what happens when important warnings are dismissed: tolerance of preventable danger can have devastating consequences. In life and faith, not all tolerance is good; sometimes, what we allow to persist can quietly undermine what matters most. In Revelation 2:18-29, Jesus addressed the tolerant church—affirming the good, but warning of the perils of tolerating sin and false teaching. Christ’s words bring encouragement, correction, and promise to all churches, urging us to discern between commendable patience and damaging negligence. Good tolerance builds community; bad tolerance can erode faith.
