This is central, critical, definitive.
One aspect of the Trinity, something at the heart of the wonderful 17th chapter of John is that relationship O(Love) is already fulfilled and perfected within the Godhead, and that we are given the grace to enter the very heart of God by growing in unity with one another.
Someone might read your 'thought' and dismiss it as sort of 'what I learned in kindergarten.'
But in truth it is absolutely central to the Gospel. When God says, "Let there be light," when we say, "Amen! Come Lord Jesus!" we are proclaiming relationship. God Himself is giver, recipient, gift -- Lover, Beloved, and Love. Relationship.
Amen! Come Lord Jesus!
In my parish, in a brief, quiet moment before the priest steps down to give Communion, the choir chants very softly
“God is love and he who lives in love lives in God
God is love and he who lives in God lives in love”
I once heard a beautiful sermon by a Protestant pastor. It was about relationships—
“fulfilled and perfected in the Godhead”, as you have posted here. He ended this great sermon by remarking that the value and beauty of the Sabbath was that on that day God “rested” and that one reason why we were given the Sabbath to rest was to be IN RELATIONSHIP—with Him and with those He has given us to love.
It’s interesting to me how I have discovered—in the frailty of my old age-—that there are some things that I have heard people say that I cannot forget. That, too, is a lesson for all of us: that what we say is important, because someone may remember it for a lifetime.
