In a sermon, delivered at the 3ABN Pillars of Prophecy seminar Stephen Bohr presents the theme of the prophetic book of Daniel. All students of prophets will tell you that the two main books on prophecy are Daniel and the book of Revealtion. You cannot understand properly the book of Revelation unless you understand the book of Daniel as most of the symbolism of Daniel are found in the book of Revelation.
In beginning to study the book of Daniel, the best starting place is to study its theme so that we do not miss the main aim of the book or the big picture. Once we understand the theme all the other puzzles will fall into place. That is precisely the main thrust of the video below.
