When you pray why do you only pray to A men or A women ? Why only one sky figurine ?
Isn't 'god' meant to be 'omnipotent' therefore 'all things' all at the same time? That would mean 'amen' and 'awomen' are disengenous to singularise the affirmation but that's christianity to a tee anyway so why let the facts get in the way of a good story. ;-)
One of the reasons I will never ever 'swear' on/over/near a bible in court or anywhere else where such a statement is required.
