Job looks for hope in his suffering and is stripped of all false hopes. He's left clinging for hope in a heavenly witness who will speak for him and begs for a pledge or guarantee to be given as he waits.
Job longs for what we have in Christ. We have a heavenly witness who will speak for us at that great day. And we also have a guarantee in the Spirit of God given to us.
May we see that we have what we need to endure suffering and be equipped for death defying missions.
