My people couldn't have survived slavery without having hope that it would get better. And there's some songs from the 19th and 18th century that say [sings], "By and by, by and by, I will lay down, this heavy load." And I mean, so many songs that spoke of hope and understand it better by and by. Amazing songs. So that the slaves, just knowing that he, she, did not have the right legally to walk within one inch away from where the slave owner dictated, and yet the same person, wrote and sang with fervor, "If the lord wants somebody, here am I, send me." It's amazing.
