● Is Jesus the “mediator” only for anointed Christians?
... At a time when God was selecting those to be taken into that new covenant, the apostle Paul wrote that Christ was the “one mediator between God and men.” (1 Tim. 2:5) Reasonably Paul was here using the word “mediator” in the same way he did the other five times, which occurred before the writing of 1 Timothy 2:5, referring to those then being taken into the new covenant for which Christ is “mediator.” So in this strict Biblical sense Jesus is the “mediator” only for anointed Christians.

In what sense does Paul use the term “mediator” when referring to Jesus at 1 Timothy 2:5, 6?
In this text, Paul uses the Greek word me·si′tes for “mediator,” which term has a legal significance, so he is not using this word in the broad sense common in many languages. Hence, Paul is not saying that Jesus is Mediator between God and all mankind. Rather, he is referring to Christ as legal Mediator of the new covenant, which laid the basis for Christ’s anointed followers to share with him in his heavenly Kingdom. (2 Corinthians 5:1, 5; Ephesians 1:13, 14; Hebrews 8:7-13)—8/15, pages 30, 31.

The original-language word translated “mediator” is a legal term. It refers to Jesus as a legal Mediator (or, in a sense, an attorney) of the new covenant that made possible the birth of a new nation, “the Israel of God.” (Gal. 6:16) This nation is composed of spirit-anointed Christians, who form a heavenly “royal priesthood.” (1 Pet. 2:9; Ex. 19:6) The Law covenant, with Moses as mediator, was not able to produce a nation like that.

What about those who are not in the new covenant, those who hope to live forever on earth, not in heaven? While not participants in the new covenant, these are beneficiaries of it. They receive forgiveness of their sins and are declared righteous as God’s friends. (Jas. 2:23; 1 John 2:1, 2) Whether we have a heavenly hope or an earthly hope, each one of us has good reason to appreciate Jesus’ role as the Mediator of the new covenant.
