Maturity is ... Maximizing Diversity

Human beings have a dramatic tendency to live in "homogenous units." That is, we seek out other people with our same skin color, language, religious views, political preferences, socio-economic status, etc. etc.
       We do this unconsciously, it's like breathing.
       But that's not what God envisions for His Kingdom people. On the contrary, it seems that God is all about maximizing diversity. Why would Jesus do this? Is he crazy? Perhaps it is because we learn to love best when we would otherwise disagree most.
       I think this means that Republicans and Democrats are to respectfully disagree politically and cultivate relationship;
       I think this means that wealthier people and the economically poor are to rub shoulders and "do life" together;
       I think it means that multi-ethnic communities offer a great opportunity to humble ourselves to listen to others and learn from their worldviews.
I think this is the picture that Jesus paints of the Kingdom of God. I so desire to live with this kind of diversity.
