All forward progress is marked by unity. When people get together, for good or bad, to accomplish something, big things happen. In Genesis 11 God complimented a people for working together, even though their work was not His will.
There are many ways for human being to dwell together. Everyday around the world, people choose to live together in strife. Others struggle to overcome the domination of anger in relationships. Many endure the core people in their lives far more than they enjoy them as a gift.
