In our Christian faith, our obedience and relationship with God is manifested in our treatment of others. That is why the Israelites repeatedly received God's rebuke because in the reality of the nation's life, they neglected their responsibility towards others. The poor and marginalized experienced great oppression, while those in power accumulated more and more wealth and power. As Job tried to maintain his position as a righteous man before God, he remembered how he had been fair to his fellow man.
Job remembered how he had treated his slaves. In the ancient Middle Eastern world, it was common to own slaves. They were laborers responsible for various domestic tasks. These slaves were equivalent to a person's property so practically, they did not have any rights. Job, however, chose to treat his slaves, both male and female, differently. He allowed his slaves to be able to litigate or file legal complaints to Job as the master. What Job did was based on his responsibility to God who would later hold him accountable for everything he had done.
Treatment of the poor, widows and orphans also became Job's concern. The call is also to reject Eliphaz's opinion about him, which states that the calamity faced by Job is God's punishment because of Job's arbitrariness towards the unfortunate people in his community. In verses 16-20, Job positions himself as the father and protector of the poor, widows, orphans. His actions were based on responsibility and gratitude for all the blessings that God had given him. Despite the temptation to abuse his power, Job never flinched and always did what was right before God.
Friends of the Bible, Job's call is also a reminder for us to always do justice to others and care for those who are marginalized in society. That is the best response we can make to the justification and salvation that God has brought into our lives. God is the owner of life who invites us to realize good stewardship over life and all of His creation.
