Why the Trinity explains everything

Yesterday I began reflecting on why it is so important to believe in the Trinity.  One writer has noted this about the Trinity - "To attempt to comprehend the Trinity, you will lose your mind, to deny the Trinity, you will lose your soul".  The Trinity is so vital to the Christian faith, and even some of most basic truths of life, that without the Triune God - life as we know it would cease to make sense.

Life requires both unity and diversity
Have you ever thought about how much we as human beings crave unity, and yet we need diversity?  All good art depicts the artist's sense of unity of a given theme, and yet diversity in color.  Scientists use the term "universe" to describe the world we live in - since the word itself is a combination of two words - "unity" and "diverse".  We have planets, stars and moons, and yet a unified force called gravity pervades throughout the universe

Marriage operates on unity and diversity
Marriage itself is described in scripture as a "unity" and "diversity".  In Genesis 2:24 we read these words - "For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh."  Two people, with two personalities, male and female, come to marriage as a diversity.  However in the marriage union, both physically and otherwise, the Bible states they are at the same time "one" - a unity.  These two seemingly opposite ideas function in harmony with one another.  Without either, marriage would be impossible - with both ideas, marriage alone constitutes the most robust relationship among human beings.

The church operates on unity and diversity
1 Corinthians 12:12 gives the following description of the church - "For even as the body is one and yet has many members, and all the members of the body, though they are many, are one body, so also is Christ."  How can the church of God be "one" and "many" at the same time?  The Lord Himself provides the unity, while the gifts He gives to the true believers making up its membership provides the diversity.  Imagine a church where everyone was the same - you would see a very ineffective church.  Or imagine a church that focused only on its diversity - you would see utter chaos and confusion.  The church is so designed by the Lord to thrive on these two fundamental principles.

Love itself operates on unity and diversity
The great Christian thinker Augustine noted that in a love relationship, you need three fundamental ingredients - A lover, A beloved and the love shared between.  Love itself is the purest expression of this incredible concept of "unity and diversity". 

The Triune God created everything, since he Himself is "Unity and Diversity"
If this idea is undeniable in art, science, marriage, church-life and love, then why is it so hard to believe that the God who designed all things would not Himself be the ultimate source and chiefest expression of Unity and Diversity?  God is One is His being, and He is Three in His Identity.  He for instance is Eternal Love - The Father who loves, the Son who is loved and the Holy Spirit who embodies the Love between the Father and Son.  If God were only a unity - then His reason for creating all things would be because He was incomplete - which contradicts the Bible's insistence on God's own completeness apart from creation. (please compare Isaiah 43:10).  If God were only a diversity - then we would have bunch of warring gods and godesses, chaos and confusion, no order and no purpose for our world.  Only the Trinity makes sense of how it is God is at one time both "Unity" and "Diversity" - since His creation, in both its unity and diversity, bears this fingerprint of His identity everywhere.
