It seems to me that, whenever you have a large group of people attempting to decide something, nothing happens suddenly. People argue. People disagree. People walk away. People want their way. Yet when a certain king made the decision to turn Judah away from the idols and return to the God of their fathers, something happened.

And Hezekiah and all the people rejoiced because God had prepared for the people, for the thing came about suddenly.

2 Chronicles 29:30 (ESV)

Suddenly. A whole bunch of people did the same thing. It happened quickly and without argument. John Gill’s Exposition of the Bible says this:

And Hezekiah rejoiced, and all the people 
To see things go on so well, which foreboded good unto them: and particularly that God had prepared the people;
disposed and directed their hearts in such a manner as to yield such a cheerful obedience to the will of God, and show such a hearty regard to his worship and service, and the restoration of it: for the thing was done suddenly;
whereby it the more appeared that they were under a divine influence, which so quickly and powerfully wrought upon them to engage in this work, and needed not arguments and persuasions to bring them to it.

Simply put, God worked on the hearts of the people and they were unified in spirit and action.

Just imagine what the Church could accomplish if we put away the groups and committees and votes and relied entirely on the Holy Spirit to unify us. Not by popular vote, but by unanimous agreement in Spirit and in Truth.

And every work that he undertook in the service of the house of God and in accordance with the law and the commandments, seeking his God, he did with all his heart, and prospered.

2 Chronicles 31:21 (ESV)
