In the Old Testament the Israelites had just crossed the Red Sea in a miraculous event. Water came from the rock and many other numerous miracles had occurred. However when they came to the banks of the Jordan and saw the giants and scary people on the other side of the river their hearts were faint and they pulled back from taking the Promised Land. I maintain they had what I call the "slave mentality."
These folks had just come from many years of slavery and bowing and scraping and learning obedience from the time they were born. The will to "resist" had been trained out of them. In fact they were trained to be obedient to apparent authority just because the authority was clothed in the trappings of legality.
