I've blogged through The Matchless Love & In-being this summer here, so I thought I'd read/preach it for you if listening is easier than reading. Download: Richard Sibbes - The Matchless Love & In-being, Sermon 1, 65mins - read by Dave Bish
It's long, and in places a bit dense and hard to follow, but oh is it sweet!
I'm modernising the text a bit, latest version of that is here PDF: The Matchless Love & In-being. Even having 'preached' it I'm aware of more edits to make it more accessible, so I'll aim to update the text again next week.
