Isn't God a God of Order?

One of the doctrines of Conservative Christians have always clung to is that God put everything and everyone in place so that there are orders to things and that we should obey those in authority to keep peace. But if it's the leader himself going out of his way to put everything in chaos and flip everything upside down, it sure doesn't look like he's someone who is appointed by God for the high position.

15 “Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves. 16 You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? 17 Even so, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Therefore by their fruits you will know them. Matthew 7:15-20
