Unifying
As Bird says, "He binds people together in one fellowship by uniting them with Christ and with each other". If the Holy Spirit truly unifies the body of the church through racial, ethnic, economic, etc. lines, then we should be giving him the space to do so. Sometimes I have seen unity as something we have to "muscle through" ourselves. And I agree, there is much merit to the personal perseverance towards unity. But the world of Acts 2:44-47 is all but unreachable without the divine help of the Holy Spirit.
