I'm just pullin' yer leg bro UntoHim.
Since it's popular, and maybe trendy -- provoked by Lee, to distinguish himself -- to accuse Lee of modalism, discussion of the Trinity is more than welcomed here.
15:45 doesn't mention the trinity in any way. However, how can we consider the Spirit without involving the trinity? All of it a mystery.
That's why I say, fall in love with the mystery. I'm bettin' most y'all have been in love. And I'll bet women (or men) are still a mystery to you. You fell in love with a mystery.
That's why I consider being stumped about the Spirit/trinity/15:45 is a good thing. And it's good to be honest about it.
It may not completely satisfy -- especially the mind -- but it's better than just makin' something up about it; a Lee kinda thing: just make something up; and call it reality; call it: what God is doing, or did, or will do; as long as he, Lee, got the credit, of being God's one and only oracle.
I can do without all that kind of make-believe. I'd rather be stumped.
As I see it -- as I pointed out with Gen 1:2, and Matt 1:18, the Holy Spirit has been at work from the beginning. And has brought heaven to earth all along.
Does Christ play a central role in this, and in 15:45? You read your Bible. What do you think?
