A good place to begin today is to think a bit about the relationship between God the Father, God the Son, and God the Holy Spirit. They are collectively referred to as The Holy Trinity. We understand them to be One God in three Persons. How their internal relationship works is a mystery we accept more than understand.
There's a fitting parallel in a French novel from 1884 titled "The Three Musketeers". The motto of the main characters is
"All for One and One for All!"
Their motto provides an analogy, at least in part, for the internal relationship between the Father, Son, and Holy Spirit.
But I'm thinking we can go deeper than that.
