Mediator as applied to Christ, is borrowed from persons, whose office it is to reconcile such parties as are at variance, being as it were in the middle, betwixt both, soliciting the cause of each to the other, till they bring them to concord or agreement.
Shortly before He drew His last breath, Jesus Christ cried out, “It is Finished”. At that place and time He bore our sins in His body on the tree, became a curse for us and paid the debt for our sins. On the cross He completed all of the physical and spiritual sufferings needed for the salvation of mankind.
