Just as the trumpet blast during Rosh Hashanah (aka Yom Teruah) and God’s other appointments were calls to awe and joy in Heaven, so too, the resurrection and transformation on the Day of the LORD will be a happy time — for those with their hearts tuned to Heaven’s station.
Amid all the disasters foretold to be coming on the world during this time, there’s the good news that the Messiah will be bringing the misery of a sin-stained world to an end.
