"But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed."
Both passages connect Christ's suffering with the concept of bearing the 'wrath' or 'chastisement' for sin. The EGW passage directly states that wrath was crushing out His life, echoing the idea of being 'bruised for our iniquities' in Isaiah.
"Behold Him contemplating the price to be paid for the human soul. In His agony He clings to the cold ground, as if to prevent Himself from being drawn farther from God. The chilling dew of night falls upon His prostrate form, but He heeds it not. From His pale lips comes the bitter cry, “O My Father, if it be possible, let this cup pass from Me.” Yet even now He adds, “Nevertheless not as I will, but as Thou wilt.” DA 687.2"
"And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt."
The EGW passage directly quotes Matthew 26:39, making it a clear and explicit allusion.
"The human heart longs for sympathy in suffering. This longing Christ felt to the very depths of His being. In the supreme agony of His soul He came to His disciples with a yearning desire to hear some words of comfort from those whom He had so often blessed and comforted, and shielded in sorrow and distress. The One who had always had words of sympathy for them was now suffering superhuman agony, and He longed to know that they were praying for Him and for themselves. How dark seemed the malignity of sin! Terrible was the temptation to let the human race bear the consequences of its own guilt, while He stood innocent before God. If He could only know that His disciples understood and appreciated this, He would be strengthened. DA 687.3"
"Then saith he unto them, My soul is exceeding sorrowful, even unto death: tarry ye here, and watch with me."
Both passages highlight Jesus's desire for companionship and support from his disciples during his suffering. The EGW passage elaborates on the emotional and spiritual significance of this desire, connecting it to the weight of sin and the temptation to abandon humanity.
