A man who remains stiff-necked after many rebukes will suddenly be destroyed—without remedy.
We all do dumb stuff and need to be rebuked for our bad choices. But some of us just refuse to receive correction, time after time. At some point God says “enough is enough” and, as the verse says, we will be ultimately and completely destroyed. And when it happens, it will come suddenly – even at a point when we don’t expect it. Just for the record, I think the destruction here is talking about this life, not eternity.
But the Bible discusses this matter, specifically, in reference to unbelievers – a sobering discussion in Romans 1 (see :26). It is also addressed in the lives of believers, too. In 1 John 5:16, a believer finally does too much and God says “enough.”
There is such a day for any and all of us who refuse to listen – but it doesn’t have to be that way. All we have to do is get honest about our attitudes and actions and accept responsibility for our choices. At that point, we can receive forgiveness and empowerment to do the next right thing.
