Jesus is clear that there are some people we should not invest our energy and spiritual capital into. Their lives, attitudes, and behaviors make it unwise and even dangerous for us to minister to them. Jesus warns us that these people will actually turn on us, attack us, and try to "tear us to pieces." We want to think the best of everyone, but if we don't tell the truth with an accurate label, we can't get to the root issue. We risk harming ourselves.
