Ryan Bush delves into the multifaceted work of Christ as Mediator, breaking it down into two key components: Expiation and Propitiation. Using a tapestry metaphor, he explains that these two elements are like intertwined threads that together create the full picture of Christ's mediation between God and humanity.
Starting with mediation, Bush references 1 Timothy 2:5-6 to clarify that Christ serves as a mediator between God and men, bridging the gap caused by sin. Unlike an advocate, who represents one party, a mediator takes into account the interests of both conflicting parties. In this case, Christ is uniquely qualified to be our mediator because He is both fully God and fully man.
Bush then dives into expiation, the first thread in the tapestry, explaining it as the act by which Christ's blood cleanses our sins. He likens it to legal jargon, where a penalty or fine is paid to address an offense. Using biblical references, he establishes that expiation is a transaction that deals with our sins as offenses against God the Judge. The "wages of sin is death," so Christ pays this penalty through His sacrifice, effectively "nailing" our debt to the cross.
The second thread, propitiation, is described as the appeasement of the offended party—God, in this case. Referencing 1 John 2:2 and 4:10, Bush clarifies that while expiation deals with the offense (sin), propitiation is focused on the offended (God). The propitiatory work of Christ transforms God's wrath into love, changing our relationship with Him from enmity to friendship. Propitiation is relational and addresses God as the Father, not just the Judge.
To illustrate, Bush gives the example of two neighboring farmers, one of whose son accidentally sets the other’s property on fire. Even if the father of the boy compensates for the loss (expiation), the relationship remains strained until the offended farmer’s wrath is appeased (propitiation).
Bush emphasizes that understanding both elements—expiation and propitiation—is crucial for a comprehensive understanding of Christ's role as our mediator. Christ's sacrifice does not merely cleanse us of our sins (expiation); it also restores our relationship with God by turning His wrath into love (propitiation). The effectiveness of this work is due to the incomprehensible love God the Father has for God the Son.
Finally, Bush shares a moving testimony from Sarah Edwards, wife of theologian Jonathan Edwards, capturing the transformative power of understanding God's love fully. This knowledge assures believers that God's love is as steadfast for them as it is for Jesus Christ, offering both hope and peace.
Overall, Bush's podcast serves as a deep theological exposition aimed at encouraging believers to recognize the intricate, dual nature of Christ’s mediation, so that they may rejoice in the complete redemption and love they have in God through Christ.
