Until God opens the next door, praise him in the hallway. I think this quote is just a cliche and doesn't mean much to anyone until they find themselves in a hallway and see how difficult it can be to trust and praise God in times of waiting.
spiritualinspiration: “ Much of life is spent waiting. It’s how we wait that makes all the difference. Psalm says “Each morning I bring my requests to you and wait expectantly.” Waiting with expectancy means instead of worrying if God is going to.
This is so true that on the nights it isn't raining, I sleep to the sound of artificial rain. though it simply can not compare to the real thing. The best thing to fall asleep to is the sound of a raging thunderstorm.
