They are trying to rebuild the city and the temple and the people who are around Jerusalem are not happy. So when there is a new king they write to him and inform him that these people (Israel) cannot be trusted to rebuild their city because they are dangerous. The accusers tell the king to search the records and they find this is in fact true.
Gods people are a dangerous people to the world and that past will catch up to you when you endeavor to join God in what he is doing. Is your God too safe? Cause this God of Israel doesn't seem to be... and that is why the king commands a stop on the building (for now).
What kind of God do I believe in? What kind of person do I believe God is making me? I think a dangerous one. One that is dangerous to the world in the way that I love; the way that I stand for those who no one stands for; the way that everywhere I go the ideals of the world seem to collapse. That is a dangerous person to anyone who has their security in the ways of this world and they will do anything to stop you, but our God is greater and will never be stopped.
Follow the unsafe God and you will overthrow kingdoms cause God is in the business of doing so. Only one kingdom will truly stand, His.
