Matthew 8:16: “When the evening was come, they brought unto him many that were possessed with devils: and he cast out the spirits with his word, and healed all that were sick: That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses”
A friend one day told me he was coming down with flu, and yes before long he had the flew. Once something has been internalized it is only a question of time before it will happen. Don’t allow things that are not Biblical, like sickness ruin what could be a healed lifestyle. Speak things that are not as though they are.
