Proverbs 29:1 NIV
Whoever remains stiff-necked after many rebukes will suddenly be destroyed—without remedy.

“Warnings rarely come with countdowns. We can’t tell when we’ve had our last chance to change. When we, like the person in this proverb, refuse to consider valid criticism, we leave ourselves open to sudden disaster. The moment we realize that a change is necessary is the best moment to take action.”
