Well... this 'good = Jah' bad = Satan' thing is a tad too narrowminded.
I know of a lot of JWs that will recite this silly stuff.
However... how does one know if it's 'good' that it ain't a 'test of Satan'? Hmmm??? (Let's 'tempt' this moronic human)
OR! - if it's 'bad', it is a 'test of Jah'? Hmmm??? (remember the story of Job)
According to their own 'rules', it could happen.
I guess that's why I never got too much into that... 'praise Jah' nonsense.
