In those posts I assumed that the LORD of the burning bush was the very One who became incarnate of the virgin Mary. Just to say, that wasn't sloppy grammar or fuzzy thinking (I don't think!). To many of you the point is obvious but I've read enough biblical theology around the place to know that other views abound. So often you hear things like: "Jesus is the Son of the one the OT calls Yahweh." Now in one sense that is true. In the OT, the Father often goes by the name of Yahweh, just as in the NT He often goes by the name Lord. But most often 'Lord' refers to the Son - this is true in both testaments.
Jesus' claim, and the claim of the NT, is that He is Yahweh (in Greek 'kurios'), the God of Abraham, the God of the burning bush (e.g. John 8:56-58). Now the God of the burning bush is the Sent One from Yahweh ('The Angel of the LORD' Ex 3:2) and so clearly there is more than one Person called LORD. But Jesus, the Sent One of the Father, claims to be the One who calls Himself I AM.
Nowhere is Jesus ever called the Son of the Lord. Everywhere Jesus is called the Lord.
I just mention this because it seems to me that many, wittingly or unwittingly, dilute the claims of Jesus in the Gospels. But we must be aware of how radical Jesus' claims are - He's not simply saying 'I am the Son of the God of the Old Testament.' He's saying 'I am the God of the Old Testament.' The implications are many but I said I'd be brief, so there you are.
