Stellar Blade is is honestly just a criticism of blind faith without deeds. It's very common for extremely faithful christians who devote their entire lives to their beliefs then forsake it once things don't go their way or when faced with extreme hardship. It's also a jab on the fatalist take that some christians have, who forego all hope and sense of preservation and just give up their lives because 'It can't be helped' and 'God wills it'.
I'd totally bang Mother Sphere though
