Angelic protection

A friend gave me a book about Robert Chapman (1803-1902) called 'The Apostle of Love.'  Spurgeon described Chapman as 'the saintliest man I ever knew'.  On one occasion a man became so angry at Chapman's preaching that he swore to himself that he would kill him.  He knew of Chapman's walking routine and waited along a quiet road with his gun.  However the man could not get a shot because there was always another man between him and Chapman.  But Chapman walked alone.
