In theology, just as in battle, some hills are worth dying on. But how do we know which ones? When should doctrine divide, and when should unity prevail? Pastor Gavin Ortlund makes the case that while all doctrines matter, some are more essential than others. He considers how and what to prioritize in doctrine and ministry, encouraging humility and grace along the way. Using four basic categories of doctrine in order of importance, this book helps new and seasoned church leaders alike wisely labor both to uphold doctrine and to preserve unity.
