Jesus healed many who were under the power of demons with just one statement of faith. Search the Word of God for a statement of faith that applies to your situation, and speak that Word over your life daily.

When evening came, they brought to Him many who were under the power of demons, and He drove out the spirits with a word and restored to health all who were sick. And thus He fulfilled what was spoken by the prophet Isaiah, He Himself took [in order to carry away] our weaknesses and infirmities and bore away our diseases. Matthew 8:16-17 (AMPC)
