I'm sure I don't remember how it happened the first time, but I think I know how it felt. That's because it happens often, too often for my liking. Getting wedged in tight places, that is. The circumstances are always unique, which is, of course, the nature of circumstances. The tight part is the part that's always the same.
      It is a stuck sort of feeling. A feeling that begins with an "Oh No!" which at first is really more of a hopeful question, like that moment when you've just let go of something that you wanted to hold on to and you're not quite sure if you've really let go of it or not. "Oh No!" is quickly followed by "Oh Dear!" which means you are sure that you've lost it and you wish you hadn't. "Oh Dear!" is followed by a different sort of "Oh No!" the sort that is neither a question nor very hopeful. It means that you've become wedged in a tight place.
The trouble with being wedged in a tight place is that you can't get out, at least not right away. That's what makes it feel so tight. You just stay put, no matter how hard you push or how hard you pull. It's like when something terrible just happens and you're not sure how or why, only that it did and you don't know how to get back to the time before, the time when everything seemed just fine.
It is very unsettling being wedged in a tight place. Mostly because you can't do anything about it except wait and we don't like to wait much, especially when we're uncomfortable.
Pooh bear was visiting Rabbit and while he was visiting ate a rather large amount of honey. The honey settled round his middle and when he tried to get out of Rabbit's front door he got stuck. He couldn't go forward. He couldn't go back. Christopher Robin said Pooh would have to stay there for a week and couldn't eat anything at all, but that they would read to him while he waited to get thin.

"Bear began to sigh, and then found he couldn't because he was so tightly stuck; and a tear rolled down his eye, as he said: 'Then would you read a Sustaining Book, such as would help and comfort a Wedged Bear in Great Tightness?'
So for a week Christopher Robin read that sort of book at the North end of Pooh while Rabbit hung his washing at the South end."

"Cast your cares on the Lord and he will sustain you;"          Psalm 55:22a

Our Sustaining Book is mostly about Wedged People in Great tightness, people who couldn't do anything but wait. Our Sustaining Book is all about the One who chooses to sustain rather than destroy, comfort rather than afflict, about the One who offers us freedom from all the tight places into which we have or ever will work ourselves. Our Sustaining Book is about people reading to each other as they all wait to be set free.
Having someone read to you while you are wedged in a tight place is a very friendly sort of thing, especially under the tight circumstances, but it means you must move from saying, "Oh No!" which one says mostly to oneself, to "Oh Help!" which one says to whoever might be able to oblige. It's not as easy as it sounds because being wedged in a tight place is not the sort of thing one likes to admit to being. But none-the-less it's the only way and once it's done it's done.
A Sustaining Book and friends are the sort of thing that make the experience of being wedged in a tight place seem, somehow, less tight. Perhaps because a Sustaining Book and friends help us focus, not on what was lost, or how we lost it, or even when we might get it back, if ever, but on what we have at the moment, which is, of course, a Sustaining Book and friends.
