It is natural for humans to seek the help of a mediator or middleman. The teenage son seeks the mediation of his mother, to get concessions or privileges from an angry father. Citizens seek mediators to get things done or to deal with the government.
Israel: God delivered Israel from Egyptian slavery. Moses led them as God divided the Red Sea. God provided them with manna and water as miraculous provisions. They also defeated the Amalekites. Then they moved to the wilderness of Sinai. As commanded by Moses, they consecrated themselves and waited in their tents. God’s presence was displayed as signs of thunder, lightning, smoke, clouds, and earthquake. The Israelites trembled, there was a long trumpet. Moses led the people up to the boundary around Mount Sinai. Moses spoke and God responded. However, Israel said to Moses that God need not speak with them, Moses could speak with them. Israel wanted Moses to be their mediator. (Exodus 20:18-19)
Job: Though he was certified as a righteous person by God, he had to go through suffering. Job was perplexed as to why this was happening to him. His friends accused him that he was reaping the consequences of sin. However, Job was pretty sure that he did not commit any sin and his statement of innocence is genuine. Hence, Job longs to have a mediator or arbitrator between him and God. (Job 9:33-35)
Only mediator: The human need for a mediator is fulfilled in the Lord Jesus Christ. (I Timothy 2:5) All have sinned and come short of the glory of God. (Romans 3:23) The wages of sin is death. (Romans 6:23) Lord Jesus Christ took the sentence of death on Himself as the Lamb of God who takes away the sin of the world. (John 1:2) He as the Eternal High Priest took His own blood, entered the Most Holy Presence of Father, and sat on the right hand of God. (Hebrews 10:12) Apostle John states He is our advocate. (I John 2:1) Angels, dead apostles, or saints cannot be mediators for us.
Do I rejoice and thank Lord Jesus our mediator?
