Job feels compelled to unburden himself even though there is risk that in doing so he will only be hurt even more, since those with him are incapable of sympathy and have used everything that he has said in his defence as a weapon against him. What he needs is someone who is truly going to be for him and can weigh up his words without prejudice.
As Job considers his predicament, he can only tremble at the thought of what God is doing to him. Sometimes the friends of God suffer the sharpest trials and most face the most searching questions. This teaches them to resolve all of their own wisdom into the wisdom of God and to submit their minds to him who knows all things and cannot be mistaken.
When depressed we are not able to field assaults on our faith which insist: ‘You are not a believer’. In themselves they are no proof of the judgement of God. We will know if we are really sinning against God, but time after time we are too hasty to believe that all is not well with our own souls.
The question at the start of verse 4 implies an answer which is not expressed: ‘No, my complaint is not against man but against God.’ What follows assumes that answer, and explains why Job is defending the severity of his situation. He is saying, ‘If my complaint is against God’, or, ‘Since my complaint is against God’, or, ‘If this is what I am having to suffer, then are you surprised that I am deeply troubled?’
