Our Redeemer Lives
Job 19:25–26 (ESV) … “For I know that my Redeemer lives, and at the last he will stand upon the earth. And after my skin has been thus destroyed, yet in my flesh I shall see God…”
Job expressed confidence that, even if he died, he would still have a Redeemer who one day would exercise judgment on the earth. Furthermore, Job affirmed that he himself expected to live again and see his Redeemer! “And after my skin has been destroyed, yet in my flesh I will see God” (v. 26, NIV). It was an affirmation of faith in the resurrection of the human body.
The Hebrew word translated “Redeemer” in verse 25 refers to the kinsman redeemer, the near relative who could avenge his brother’s blood (Deut. 19:6–12), reclaim and restore his brother’s property (Lev. 25:23–24, 39–55), and set his brother free from slavery (25:25). The kinsman redeemer could also go to court on behalf of a wronged relative (Prov. 23:10–11). In the Book of Ruth, Boaz is the kinsman redeemer who was willing and able to rescue Ruth and give her a new life in a new land.
Previously, Job had talked about his need for an umpire (Job 9:33–34) and an Advocate in heaven (16:19). Now he takes it a step further: his Redeemer will one day vindicate him, and Job will be there to witness it! When you consider how little God had revealed in Job’s day about the future life, these words become a remarkable testimony of faith. And when you add to this the discouragement expressed by Job’s friends and his own intense suffering, Job’s witness becomes even more wonderful.
Of course, this kinsman redeemer is Jesus Christ. He took upon Himself a human nature so that He might reveal God to us, experience all that we experience, die for our sins, and then return to heaven to represent us before the Father. He is willing to save and able to save. One day He shall stand upon the earth and exercise judgment; and He will vindicate His own people.[1]
