I have always believed that God has given us the basic building blocks of chaos with which we have the opportunity to bring order. When we do that well, whatever the discipline - there is harmony there...whether it be a symphony of instruments or a kaleidoscope of nationalities.
This speaks of unity.
Paul says it so well in 1 Corinthians 12:12-14, 'Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ. For we were all baptized by one Spirit so as to form one body—whether Jews or Gentiles, slave or free—and we were all given the one Spirit to drink. Even so the body is not made up of one part but of many.
