Gregg Allison commenting on the Spirit as creator and sustainer of unity in the community of faith:
“Churches do not have to attempt to create unity among their members; the Spirit provides that for them (Eph. 4:3). What must instead happen is that churches are to work hard to maintain that unity, which seems to be fragile and undergo breakdowns because of the sinfulness of church members (Eph 4:30; 1 Thess. 5:19).
Mindful that they are natural enemies who have been brought together not naturally but by the grace of God through Jesus Christ, church members rely on the Holy Spirit to be able to express genuine love toward one another (Rom. 15:30; Col. 1:8) in an atmosphere of righteousness, peace, and joy fostered by the Spirit (Rom. 14:17).”
