A scholarly 19 page document concludes that "Christ is not mediating today." It is true that his work as a mediator in shedding his blood has been done (Ephesians 1:7), and "there remaineth no more sacrifice for sins" (Hebrews 10:26). He will not come and die again.

But through his representatives, the apostles and today all Christians, as they appeal to sinners, "Be ye reconciled to God," are speaking "in Christ’s stead" (2 Corinthians 5:20). They are saying what Christ would say if he were present:

Such words, from Christ or from his representatives, do not reflect Jesus’ work as an intercessor or advocate for Christians (Romans 8:34; 1 John 2:1). But those words, along with "Be ye reconciled to God" (2 Corinthians 5:20), reflect Jesus’ work as a mediator. Thus every sinner today, as he is baptized, is looking to Christ as his mediator. Then, later, he looks to Christ as his intercessor, his advocate (Romans 8:34; 1 John 2:1). Yes, Christ is mediating today.
