Check out the versions posted in thread 6108: Wade in the Water
Often titled "God's Gonna Trouble the Water."
Usually sung as a baptismal song, used by both blacks and whites in different versions.

I have been looking for early versions. John Wesley Work, 1915, "Folk Songs of the American Negro," is the earliest I have found so far.

Sometimes tied with "Let God's Saints Come In," in Allen, 1867, "Slave Songs..." but this spiritual doesn't have the 'wade in the water' line.
Come down, angel and trouble the water (3x), And let God's saints come in.'
