It has now become almost clear that the book belongs either to the period (favoured by Ewald, Renan, and others) immediately following the captivity of the northern tribes, or to the time of the captivity of Judah (fixed upon by Dr. A. B. Davidson, Professor Cheyne, and others). We must still, however, seek further light by glancing at the main problem of the book, which is to reconcile the justice of Divine providence with the sufferings of the good, so that man may believe in God even in sorest affliction. We must also consider the hint of time to be found in the importance attached to personality, the feelings and destiny of the individual and his claim on God. Taking first the problem,--while it is stated in some of the psalms and, indeed, is sure to have occurred to many a sufferer, for most think themselves undeserving of great pain and affliction,--the attempt to grapple with it is first made in Job. The Proverbs, Deuteronomy, and the historical books take for granted that prosperity follows religion and obedience to God, and that suffering is the punishment of disobedience. The prophets also, though they have their own view of national success, do not dispense with it as an evidence of Divine favour. Cases no doubt were before the mind of inspired writers which made any form of the theory difficult to hold. But these were regarded as temporary and exceptional, if indeed they could not be explained by the rule that God sends earthly prosperity to the good, and suffering to the bad in the long run. To deny this and to seek another rule was the distinction of the author of Job, his bold and original adventure in theology. And the attempt was natural, one may say necessary, at a time when the Hebrew states were suffering from those shocks of foreign invasion which threw their society, commerce, and politics into the direst confusion. The old ideas of religion no longer sufficed. Overcome in war, driven out of their own land, they needed a faith which could sustain and cheer them in poverty and dispersion. A generation having no outlook beyond captivity was under a curse from which penitence and renewed fidelity could not secure deliverance. The assurance of God's friendship in affliction had to be sought.
