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 a 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).
