For there is one God and one Mediator between God and men, the Man Christ Jesus.
1 Timothy 2:5
The backlog of cases to be tried in American courts is so severe that alternative means of conflict resolution are gaining acceptance, the most popular being mediation. In mediation, an objective, neutral third party—agreed upon by the two parties in dispute—hears particulars of a conflict and tries to mediate a resolution. That is, they guide the two parties toward a solution using compromise and new ideas—a solution both parties can live with.
A mediator was needed to satisfy the claims of a holy God against sinful humanity. From God’s perspective, holiness couldn’t be compromised. From man’s perspective, payment required death. The Father sent His Son to be Mediator between God and man—holy God living a sinless life and dying an undeserved death so sinful man might live. This was an “out of the box” solution unheard of in religion before or since—God would mediate His own dispute by being just and the justifier at the same time.
God the Father expressed His satisfaction with the Mediator’s work by raising Him from the dead. His death paid for sin; His resurrection provided for life.
The saved are singled out not by their own merits, but by the grace of the Mediator.
