I have been reading Christian Shwarz’s ideas on Natural Church Development, and one of the ideas that he has been working on, based on his working with a range of different denominational churches, is that of recovering a practical application of our belief in the Trinity. He connects green with God as Creator, red with God as Saviour, and blue with God as the indweller (the Holy Spirit). For more detail on this, have a look at this pdf. These do not directly equate to Father, Son, and Holy Spirit, but help us to think about where we are in our relationship with God:
a. Where am I rationally, i.e. in view of my thinking?
b. Where am I emotionally, i.e. in view of my heart?
c. Where am I socially, i.e. in view of my network of relationships?
God’s revelations always aim at establishing a relationship. In all three revelations we encounter the one God, but each time we encounter him in a different way. His threefold communication with us, which should correspond with a threefold response on our part, is fundamental to the nature of God as revealed to us in the Bible. Whenever just one of the three dimensions is neglected, we have an incomplete experience of God. We will come to see that most problems with which we struggle in the everyday life of our churches are, in the final analysis, based on an incomplete understanding of the threefold revelation of God.
