Rather late in coming into this thread but there is an interesting comment concerning angels in a short booklet entitled, ‘Christ on Trial in Zimbabwe-Rhodesia’ written by a man called Tom Barlow. Set in the time of the bush war in Zimbabwe there is a passage which tells of how some freedom fighters approached a farmhouse late at night, the intention being to attack the property and kill the occupants. The farming family were Christians. But the men withdrew without pressing their attack. When asked later for the reason for their withdrawal their answer was that the farmhouse was completely surrounded by men in white standing guard over it.
"For He will command His angels concerning you, to guard you in all your ways."
