How do we know Job was a righteous man?

Job is described in the Scriptures as a righteous man, as affirmed by the Lord in Job 1:8, where He says, 'Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man?' This designation is crucial because it illustrates that Job's righteousness was not based on his own actions or merit but was a result of God's sovereign will and grace. Despite experiencing profound suffering, Job's status as a vessel of mercy underscores how God maintains and sustains His people during trials.
