Sometimes two estranged parties need a third person, sympathetic to both, who can bring them together. Job lamented in 9:33 of his relationship with God: “There is no umpire between us who may lay his hand upon us both.” In other words, he didn’t have a mediator!
What Job calls an “umpire” or a “mediator” is just what Jesus has become for us. I Timothy 2:5 says “For there is one God, and one MEDIATOR between God and man, the Man Christ Jesus. Jesus has the ability to “lay His hand upon us both”, for He “touches” both God and Man: from the beginning He has been God (John 1:1) and He became Man to be able to intercede for us (Heb. 2:17). As such He is the perfect “umpire” or mediator who can “lay His hand upon us both” and resolve the differences between men and God, and bring us back together.
What Job only wished he had — an “umpire” or mediator who could “lay his hand upon both” to bring him and God back together — we do in fact have in Christ Jesus. “Therefore let us draw near with confidence” through Him! (Hebrews 4:16)
