Like there are thin lines between:

Spiritual passion and mental instability.

Doctrinal purity and judgmental hypocrisy.

Social justice ministry and works without faith.

National / Regional pride and idolatry.

Attention to detail and obsessive compulsion.

Having a “prophetic ministry” and being a jerk to the congregation you serve.

Having a “pastoral ministry” and being an enabler to the congregation you serve.

Sarcasm and cruelty.

Confidence and arrogance.

Open minds and empty heads.
