“For there is one God and one mediator between God and men, the man Christ Jesus” (1 Tim 2:5)
Elder Jeffrey R. Holland taught: “Mediation is required when there is dispute or disagreement between two or more people or parties… Christ’s role as Mediator is a privilege of His birth as the Son of God and His Atonement, which won Him the right to speak on behalf of others.
Other related roles such as advocate and counsel, both of which are legal terms, underscore the fact that “cases” will be brought before the bar of eternal justice, and the defendants need representation. Christ is our representative in those proceedings and will seek reconciliation with Heavenly Father on behalf of His mortal children, all of whom have transgressed and lost their own standing before the bar of justice.”
Elder Boyd K. Packer gave a well known address titled ‘The Mediator’ in which he explained Christ’s role in mediation and why we need it.
“Unless there is a mediator, unless we have a friend, the full weight of justice untempered, unsympathetic, must, positively must fall on us. The full recompense for every transgression, however minor or however deep, will be exacted from us to the uttermost farthing. But know this: Truth, glorious truth, proclaims there is such a Mediator.
…our burdens of disappointment, sin, and guilt can be laid before Him, and on His generous terms have each item on the account marked, “Paid in Full.””
