The difference was than thin RED Line...
The foreshadowing of the saving Blood of Jesus
Rahab was told to put a RED string in her window so she and her family would not be killed by the Hebrews whan they attacked the city...
That meant she had to trust in the idea of that type and shadow of Blood to save her instead of her pagan household gods...
This is a type and shadow of the salvation of the NT because she had to trust the Hebrew spies and their God represented by that RED string...
Havent you ever wondered why she was told to use a RED one ???
Theres so much in that story that foretells Jesus...
But ya have to finally read it for yourself...
BTW Because of her faith Rahab is in the Hall of Fame in the 11th Chapter of Hebrews...
right in there with Abraham and Moses...
They didn't have lightbulbs then? ;^)
