Lysa TerKeurst shares a very personal story about how setting a boundary around her spiritual capacity changed her life. She realized that there were limits to how much she can give, and that when she gave too much, she couldn't function. It's a form of people-pleasing that caring people will have to confront. Setting this boundary allowed her to shift from a place of trying to have control over how other people feel, to a place of compassion, and it ultimately helped save her marriage.
