What does the Bible say about Job's righteousness?

In the book of Job, he is described as 'a perfect and upright man, one that feared God and eschewed evil' (Job 1:1). However, from a sovereign grace perspective, it must be understood that Job's righteousness was not inherent but was attributed to him because he was in Christ. Outside of Christ, all men are sinners. Thus, Job's designation as perfect demonstrates the righteousness that believers receive through faith in Jesus Christ, who fulfills the law on their behalf. This illustrates the grace by which God sees believers as righteous, despite their sinful nature.
