The Feast of Trumpets represents many things: The first resurrection, the return of Christ, and the Yom Teruah, "a great noise, shout, or blast". Trumpets also foretells of the 7th Trumpet, the Day of The Lord, a great and dreadful day. The difference in whether the coming of the Lord is great or dreadful for each of us, depends on how we are found when He comes.
Supplemental song to listen to after the sermon.
