What is the Holy Trinity?

Did you ever think about what the Holy Trinity is?  Yes, we know it is the God the Father, Son, and Holy Spirit.  Yes, we know that it is three persons in one God.  But really, besides that what are they?  They are the way God reveals himself to us.  We see Him in the result of creation.  We see Him in our Savior, Jesu Christ, and we see Him in the good that surrounds us.  God is everywhere.  Always coming, always breaking out, always finding new ways to reveal to us that something else besides ourselves is going on.  Also, in the Trinity, the most important characteristic about God is revealed: Relationship.  God enjoys and thrives in the eternal relationship of God in the Trinity.  Perhaps that is a good example for us as we enjoy and live in our relationships too.
As we celebrate our Holy Trinity birthday party, think about what the Holy Trinity mean to us.  What is about the Holy Trinity that guides us or grounds us?  What do we have in the guiding light of a name for our community as Holy Trinity Lutheran Church?
