"He sent his word" speaks of God sending His Word. It is the sent word that brought healing. Not just any word, but a sent word. "Sent" (Hebrew: shalach, shaw-lakh') means the appointed or the assigned word. You will find that it is the appointed, the assigned word God gives us that brings the benefit. It is the sent word that brings the healing. It is the sent word that brings the deliverance. It is the sent word that brings the prosperity. It is the sent word that brings us out of where we have been into where we need to go. It is the sent word, the assigned word, the appointed word, the now word, the fresh word, the fresh rhema, the fresh manna that God has released for an appointed time for an appointed purpose that brings an appointed blessing.
