"Physical disease, however malignant and deep-seated, was healed by the power of Christ; but the disease of the soul took a firmer hold upon those who closed their eyes against the light. Leprosy and palsy were not so terrible as bigotry and unbelief. DA 271.1"
"But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house."
Both passages contrast physical healing with spiritual blindness/unbelief. EGW amplifies the idea that spiritual maladies are more dangerous than physical ones, which aligns with the implied message in Matthew 9:6 where Jesus demonstrates power to forgive sins alongside physical healing.
In the home of the healed paralytic there was great rejoicing when he returned to his family, carrying with ease the couch upon which he had been slowly borne from their presence but a short time before. They gathered round with tears of joy, scarcely daring to believe their eyes. He stood before them in the full vigor of manhood. Those arms that they had seen lifeless were quick to obey his will. The flesh that had been shrunken and leaden- hued was now fresh and ruddy. He walked with a firm, free step. Joy and hope were written in every lineament of his countenance; and an expression of purity and peace had taken the place of the marks of sin and suffering. Glad thanksgiving went up from that home, and God was glorified through His Son, who had restored hope to the hopeless, and strength to the stricken one. This man and his family were ready to lay down their lives for Jesus. No doubt dimmed their faith, no unbelief marred their fealty to Him who had brought light into their darkene…
"And immediately he rose up before them, and took up that whereon he lay, and departed to his own house, glorifying God."
EGW's description of the healed paralytic closely follows the narrative in Luke 5:25, including details like carrying the couch and glorifying God. It's a clear retelling with added details and emphasis.
