The Trumpets

For what purpose are the review or summary sections written? What was the significance of the hail mixed with blood? How is the LORD's sovereign rule the message of this book to show Christ is reigning regardless of whether they can see Him? Have they been able to take Scripture reading and true prayer out of the schools? Are these things meant for the destruction of all? What part of this world are men in control of? Is God angry every day? Why does the LORD use symbolic language?
