8 Hence, the ransom sacrifice is fundamental to the new covenant, of which Jesus is the Mediator. Paul wrote: "There is one God, and one mediator between God and men, a man, Christ Jesus, who gave himself a corresponding ransom for all-this is what is to be witnessed to at its own particular times." (1 Timothy 2:5, 6) Those words especially apply to the 144,000, with whom the new covenant is made.[…]
11 Nevertheless, in a preliminary way, the great crowd have already "washed their robes and made them white in the blood of the Lamb." (Revelation 7:14)Christ does not act as Mediator of the new covenant toward them, yet they benefit from this covenant through the work of God's Kingdom. Christ still acts toward them, however, as High Priest, through whom Jehovah can and does apply the ransom to the extent of their now being declared righteous as God's friends. (Compare James 2:23.) During the Millennium, they will gradually "be set free from enslavement to corruption [until finally they] have the glorious freedom of the children of God."—Romans 8:21.

• Is Jesus the "mediator" only for anointed Christians?The term "mediator" occurs just six times in the Christian Greek Scriptures and Scripturally is always used regarding a formal covenant.Moses was the "mediator" of the Law covenant made between God and the nation of Israel. (Gal. 3:19, 20) Christ, though, is the "mediator of a new covenant" between Jehovah and spiritual Israel, the "Israel of God" that will serve as kings and priests in heaven with Jesus. (Heb. 8:6; 9:15; 12:24; Gal. 6:16) 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.The new covenant will terminate with the glorification of the remnant who are today in that covenant mediated by Christ. The "great crowd" of "other sheep" that is forming today is not in that new covenant. However, by their associating with the "little flock" of those yet in that covenant they come under benefits that flow from that new covenant. During the millennium Jesus Christ will be their king, high priest and judge.

16 Just as the ancient nation of Israel was in a covenant relationship with Jehovah God through the mediator Moses, so the nation of spiritual Israel, "the Israel of God," has a covenant relationship through a mediator. (Galatians 6:16) It is as the apostle Paul wrote to his Christian fellow worker: "There is one God, and one mediator between God and men, a man, Christ Jesus." (1 Timothy 2:5) Was Moses the mediator between Jehovah God and mankind in general? No, he was the mediator between the God of Abraham, Isaac, and Jacob and the nation of their fleshly descendants. Likewise, the Greater Moses, Jesus Christ, is not the Mediator between Jehovah God and all mankind. He is the Mediator between his heavenly Father, Jehovah God, and the nation of spiritual Israel, which is limited to only 144,000 members. This spiritual nation is like a little flock of Jehovah's sheeplike ones.—Romans 9:6; Revelation 7:4.
