A mediator is someone who intervenes--someone who conveys and conciliates. The word "mediator" is not found in the Old Testament, but its principle is God gave the Law to the people through a mediator, Moses (Gal. 3:19), who was a type of the true mediator, Jesus. The word occurs only a few times in the N.T.: 1 Tim. 2:5; Heb. 8:6; 9:15; 12:24. It is in the N.T. that the true nature of mediation is understood in the person of Jesus Christ. He is the mediator of a better covenant (Heb. 8:6). He was able to become our mediator by becoming man (John 1:1, 14) and dying as our substitute (1 Pet. 1:18, 19; 2:24). He reconciled us to God (Eph. 2:16).
