This verse is the greatest summary of what the Lord would suffer in atoning for man’s sins given before His mortality. King Benjamin is given this instruction because God wants all mankind to understand the great sacrifice made by the Lord Omnipotent.
Christ suffered “even more than man can suffer, except it be unto death” as part of the burden He bore. (Mosiah 3: 7.) What was the burden?
First on the angel’s list is “temptations.” Isaiah would call it “our griefs” and “our sorrows” and “our transgressions” and “our iniquities.” (Isa. 53: 4-5.) Alma would call it “afflictions and temptations of every kind.” (Alma 7: 11.) Paul explained how He “who knew no sin” was made “to be sin” for our sake. (2 Cor. 5: 21.) In other words, though Christ was not personally responsible for any transgression, He was made accountable for every one of all our transgressions. He was made “to be sin” and to feel the loathsome filthiness of our unworthiness before God.
Mormon had been in the Lord’s presence. He knew how painful it was to be before God in our fallen and guilty state. Mormon explained how terrible it is to bring the weight of your own sins into God’s holy presence. He describes it as “under a consciousness of your guilt” and “a consciousness of guilt that ye have ever abused his laws” and “more miserable to dwell with a holy and just God, under a consciousness of your filthiness before him, than ye would be to dwell with the damned souls in hell.” (Mormon 9: 3-4.) He explains that in God’s presence “ye shall be brought to see your nakedness before God” and it “will kindle a flame of unquenchable fire upon you.” (Mormon 9: 5.) Since Mormon had been there, and knew what it was like to behold God’s holy presence, he understood the great challenge we all face if we do not repent.
When the prophet Isaiah was brought into God’s presence he collapsed in guilt and anguish, proclaiming, “Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the Lord of Hosts.” (Isa. 6: 5.)
Beholding God brings with it the keenest appreciation of your own unworthiness before Him so it is possible to understand He is a “just and holy Being” in whom there is no darkness.
Christ succumbed to no temptations. Yet He was made to feel the guilt and misery of all mankind’s great surrender to sin. Christ explained what that involved when He declared: “repent, lest I smite you by the rod of my mouth, and by my wrath, and by my anger, and your sufferings be sore–how sore you know not, how exquisite you know not, yea, how hard to bear you know not. For behold, I, God, have suffered these things for all, that they might not suffer if they would repent; But if they would not repent they must suffer even as I.” (D&C 19: 15-17.) Christ, looking back on His atonement, called the pain of it “exquisite” and “hard to bear” from a distance of two millennia.
The scriptures tell us how His suffering was accomplished. As He knelt in prayer, He was visited by a “just and holy being” to borrow Mormon’s words. (Luke 22: 43.) There, in the presence of the Father, Christ struggled through all the guilt, sorrow, nakedness, consciousness of guilt, and torment of being sinful, unworthy, unclean, and having ever transgressed the law of God. It was an unquenchable fire of emotion and pain, torment of mind, and recognition of failure before God. He, like all the wicked, “trembled because of pain” and “shrank” away from God in horror at His condition. (D&C 19: 18.)
Abraham was on the mount with the knife in his hand at the sacrifice of Isaac, and God the Father was present at the sacrifice of His Son. Indeed, Christ’s sufferings required the Father to be present in order to reconcile man to the Father. It was the presence of the Father that made the suffering possible. Therefore, we know the identity of the unnamed angel in Luke. (Luke 22: 43.) Christ could not have suffered the guilt of all mankind in the presence of a just and holy God, unless during this moment of torment His suffering was before that very Being.
