Passage
Instruction is grievous to him that forsaketh the way of life: he that hateth reproof shall die.
Instruction is grievous to him that forsaketh the way of life: he that hateth reproof shall die.
Proverbs 15:8 The victims of the wicked are abominable to the Lord: the vows of the just are acceptable.
Proverbs 15:9 The way of the wicked is an abomination to the Lord: he that followeth justice is beloved by him.
Proverbs 15:10 Instruction is grievous to him that forsaketh the way of life: he that hateth reproof shall die.
Proverbs 15:11 Hell and destruction are before the Lord: how much more the hearts of the children of men?
Proverbs 15:12 A corrupt man loveth not one that reproveth him: nor will he go to the wise.
The verse centers on "instruction", "grievous", "forsaketh", "life", "hateth", "reproof", and "shall". It is saying that the verse draws attention to "instruction" and "grievous", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "The way of the wicked is an..." into verse 11's "Hell and destruction are before the Lord...", so "instruction" and "grievous" belong inside that flow. In Proverbs context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "instruction" and "grievous" with trust shaped by these words, not by a vague optimism outside the passage.
