Hannah's song is a powerful piece of protest against injustice, and praise for the God Who raises the vulnerable, the voiceless, the hopeless and the hurting. Her song becomes the paradigm under which the rest of the Books of Samuel function (not to mention the rest of God's work with humanity).
Near the end, Chris gives an impassioned plea for Alberta as a province to stop being the ones who increase the suffering and hardships of our most vulnerable populations in schools, hospitals, Child Services, and other places. We have a chance to, like Hannah, seek the God Who Raises those whom society deems lowly.
There's also some low key rapping, if you're into that!
