Unless and until "We The People" make our best attempts to remove Obama, and fail, would it seem okay to pray he is removed by other means, re illness, if he doesn't repent and change.
We haven't done that. So is the fault his/that of the administration alone? Nope. We share in any guilt to be had due to our inaction.
It IS we the people, not s/he the president who are supposed to control our government, who is in it, stop wrong.
Is that a common prayer request for you? That our President contracts an illness serious enough to remove him from office? What is the matter with you?
