"Christ is the true head of the medical profession. The chief Physician, He is at the side of every God-fearing practitioner who works to relieve human suffering. While the physician uses nature's remedies for physical disease, he should point his patients to Him who can relieve the maladies of both the soul and the body. That which physicians can only aid in doing, Christ accomplishes. They endeavor to assist nature's work of healing; Christ Himself is the healer. The physician seeks to preserve life; Christ imparts life. MH 111.2"
"Heal me, O Lord, and I shall be healed; save me, and I shall be saved: for thou art my praise."
Both passages connect healing with God. Jeremiah 17:14 is a prayer for God's healing, while EGW emphasizes Christ as the ultimate healer, going beyond what human physicians can do.
"But when Jesus heard that, he said unto them, They that be whole need not a physician, but they that are sick."
Both passages discuss the role of a physician and relate it to Jesus' healing ministry. While Matthew 9:12 is about who needs a physician, EGW uses the concept of a physician to illustrate Christ's role as the ultimate healer.
