Someone who gets people's hopes up with talk about unity and peace. Someone who gives people a false sense of morale, which doesn't really do anything for them.
At least if the guy/girl who wasn't a morale booster/motivator wasn't going to do anything for anybody else, he didn't lie to them to make them feel like everything was going to be better than it was. Lighting a fire under somebody's ass is really just a way to get somebody else do what you want them to do, or be in line with your agenda, and being a morale booster/motivator is not much different.
church hurt is where you experience a degree of distance, pain, or judgement from your church community. Essentially, you are just unable to “find your place”. This is prevalent in the Christian community, but can be extended to other religions.
Now that I am an adult I am beginning to heal from the church hurt that was inflicted on me as a child.
