How important is the Holy Day known as the Feast of Trumpets? What connection does it have with the soon-coming Day of the Lord revealed by biblical prophecy?

Examining ten scriptural uses of trumpets and how they directly relate to the future fulfillment of this Holy Day, this sermon reveals how keeping God’s ordained Festivals is essential for our salvation—through them, God gives us a preview of the world-shaking events that will come to pass in the imminent future.
