Introduction to Job

This book is so called from Job, whose prosperity, afflictions, and restoration, are here recorded. He lived soon after Abraham, or perhaps before that patriarch. Most likely it was written by Job himself, and it is the most ancient book in existence. The instructions to be learned from the patience of Job, and from his trials, are as useful now, and as much needed as ever. We live under the same Providence, we have the same chastening Father, and there is the same need for correction unto righteousness. The fortitude and patience of Job, though not small, gave way in his severe troubles; but his faith was fixed upon the coming of his Redeemer, and this gave him stedfastness and constancy, though every other dependence, particularly the pride and boast of a self-righteous spirit, was tried and consumed. Another great doctrine of the faith, particularly set forth in the book of Job, is that of Providence. It is plain, from this history, that the Lord watched over his servant Job with the affection of a wise and loving father.
