For there is one God, and one mediator between God and men, the man Christ Jesus,
one mediator: A mediator is an "arbitrator" (Thayer 401), go between (Vine 54), a middle person, a peacemaker between two parties at odds or enmity with each other. For one to stand as a mediator between God and men and plead the case for reconciliation, he must have the nature and understanding of both. Therefore, Jesus, bearing the identity of God (Hebrews 1:3) and the true image or nature of man (Hebrews 2:17; Hebrews 4:15), was in himself both God and man, thus the only one qualified as a mediator for all men.
