Even as the hymn, Joyful, Joyful We Adore Thee borrows its music from Beethoven’s 9th Symphony, so does I Then Shall Live, by the Gaither Vocal Band, take its melody from Finlandia by Sibelius.
I guess it’s all right, God having given Sibelius the beautiful music in the first place.
P.S.–The hymn shop is open to one and all, so don’t be shy. If there’s a hymn you’d like to see posted on this blog, just let me know.
