G-d’s People as a Body

Been reading through the book of Isaiah and have been thinking about how G-d tells his people that he is ready to offer them mercy and grace, though his people continue to ride fast horses and run away. It’s been making me wonder if there is any difference between G-d’s people as a whole (the “Body”) and the individual people in that body.

In the past, when some of G-d’s people disobeyed to a point of no visible return, they were cut off from the rest of the Body. The Body itself still remained… but with some parts missing. It reminds me of how Jesus taught about it being better to enter into life with one eye than to have two eyes and be thrown into the fire of hell.
