I always thought this was a fairly well--known hymn. But a few years ago I had a friend who seemed surprised to see it in our hymnal, thinking it was from some other Church-related event and not knowing it had been in the very first LDS hymnal written by the first Bishop of the Latter-day church). I was decently familiar with it. Then I remember in college the boy I had a crush on singing it as a duet at Ward Prayer. Kind of permanently stuck in my mind after that. ;-) I very much love the hymn, for its own sake and not my memory's.
The tune is joyous and excited--perfect for the words about the Gospel being restored and shared throughout the world, and especially praising our King, whose Gospel it is. The third verse sings of the Millennium, and the glorious experience we shall have to be there with our Savior. My favorite lines in the whole hymn are the last two:
From the history book
There were originally 7 verses. First and second verses are the same; verses 3, 4, and 5 have been omitted because they focused mostly on the frightening events preceding the Second Coming. I am OK with that change. As much as it is good to know what those events will be, I don't really want to sing about them. Especially with such a joyous tune (which didn't actually get paired with this text until the current hymnal). The original 6th verse is not the 3rd and final verse in our hymn. But the original 7th continued with after the Millennium, fighting the adversary one more time before we spend eternity in the celestial world. Yes, I am very happy with the hymn as it is today and the German tune they picked for it.
