The Lord of the Bible?

Only by some.

Well, if some of those are Gandalf and Elrond, the chief lore masters of Middle-Earth, then I would call this rather representative.

They aren't categorically 'moments of grace' by a long way.

It is in tone with Tolkien's statement in the Silmarillion, Letters and the Atrabeth about Eru's ever-present action.

In fact there have been several threads on here discussing whether the Ring itself is sentient and has deliberately betrayed its bearer or left them.

Even if so, "behind that there was something else at work, beyond any design of the Ring-maker; I can put it no plainer than by saying that Bilbo was meant to find the Ring, and not by its maker; in which case you also were meant to have it. And that maybe an encouraging thought." Shadow of the Past

There is also the thorny topic of fate vs free will to consider

How do you consider fate would refute the position I am arguing for? Its very existence would be a manifestation of Grace, given Eru's intent - the only one who could actually decide fate.
