Ive never seen anything to indicate that they think they can force their god to something, in fact they preach patience at every turn and waiting in him and everything in his time blah blah blah....
However they may well be drinking their own cool aide and really feeling a sense of urgency and acting accordingly. Ive long said some of them are true believers and in that context it makes sense that they would feel a sense of needing to act as if the end is near
in short i would say you have cause and effect reversed.
