Are you familiar with the old gospel song, This world is not my home, I’ m just a passin through, my treasures are laid up in way beyond the blue.
I don’t know that song, but I’ll have to look it up. I think there are several with similar sentiments. Of course, the original American novel, Pilgrim’s Progress, was based on just such a theme.
And this song, http://freescripturesongs.org/beautiful-city, is I think based on Pilgrim’s Progress.
The group singing that offers a variety of free music at http://freescripturesongs.org/ichthus-music-group. I particularly enjoy “When I see the Blood.”
