Wattage, of course, is a measure of electrical power - and there is nothing more powerful than the Word of God. By the time that this Diocesan Synod is over - thousands and thousands of words will have been exchanged. Some of the words will convey faith and love and admiration. Other words may convey hurt or confusion or doubt. Still others of these words will be lost - forgotten, not heard, dumped into the passage of time like so many other millions of words uttered through the ages, and spoken on television.
Human words can exert great power.
Well, likewise, the Word of God, throughout the Bible, is incredibly powerful. The Word of God is God's communication whereby reality is changed. God's Word conveys his authoritative power. Jeremiah proclaimed that God would shatter and abandon Israel unless the people and leaders repented. They did not repent and God fulfilled His Word and Israel was utterly defeated by their enemies.
