Most of the trouble in our world takes place either when civil and ecclesiastical powers marry or merge or when civil power takes it upon itself to completely stop religion. Not all religion is legitimately pointing to the Creator God so it goes without saying that this statement does not include all religions in the most general sense of the word, but only those ordained by the Creator of mankind.
Biblical faith has its various divisions which all come together to present the full will and counsel of God to a fleeting and temporary world. There is history, law, moral and spiritual guidance, poetry, the all-important gospel message and finally about one third of the Bible is prophecy.
Pre, mid and post exilic, Messianic and pre-millennial prophecies are divisions within the general prophecies of the bible.
