In order to be purified and to remain pure, Seventh-day Adventists must have the Holy Spirit in their hearts and in their homes. The Lord has given me light that when the Israel of today humble themselves before Him, and cleanse the soul-temple from all defilement, He will hear their prayers in behalf of the sick and will bless in the use of His remedies for disease. When in faith the human agent does all he can to combat disease, using the simple methods of treatment that God has provided, his efforts will be blessed of God.” CCh 238.3-4
