Boundaries can be difficult for Christians. Sometimes we feel like we should not have boundaries and should give everything we have, including much of our time, to others. There is something heroic, martyr-like, and righteous-sounding about that idea. But this is not how Jesus lived.
How you communicate your boundaries is important. Sometimes you need to communicate your boundaries directly. Sometimes, the topic is sensitive and hard to bring up
When it comes to relationships, being able to see and respect boundaries can help you and others. Sometimes people believe they should just "give" to others and not have boundaries.
