Given the consideration above, verse 18 should probably be rendered as a question: ‘How often are they as stubble before the wind, and as chaff that the storm carrieth away?’ Very seldom, would be the implied answer. Several versions add the words ‘You say’, or similar, to the start of verse 19, making these not Job’s words, but those of the friends repeated back to them, and expressing an idea that Job very much disagrees with.
But this fact brings certain problems. There are those like the friends who choose to believe God is comprehensively judging the world right now, and that what happens to them is therefore an indication that they are approved by God. This leads to preposterous ideas about their own righteousness, and bolsters their self-righteousness. They dismiss the idea of a perfect imputed righteousness and say that man shouldn’t be so big headed is to think he can ever possess a perfect righteousness. They bring down the standards of God and make him to be one who winks at sin. It also had a bad effect on Job. His theology is right – that God’s complete judgement is far off in the future – but he is not very happy about this. We also must learn to understand, respond, learn from this, that this is not now the Day of Judgement. We must wait patiently for that. Job felt exposed to the jibes of his friends and he liked to appear to be on the victory side, but Scripture says that not till the day of judgement will it be seen that we are the children of God, and we be vindicated by God.
‘His friends wanted to convince Job that he was a wicked man, since he was so afflicted by the hand of God. This was a grievous temptation to him and very offensive. We must arm ourselves with what is set before us here, so that if God visits us and we are roughly handled by him, we may not be so overcome with confusion that despair gets the upper hand. But let us know that God does not cease to love us and pity us although he seems to be so rough for a time’ (Calvin – English updated).
