I was doing some study on Psalm 5 this morning and came across this comment by Amy Carmichael on verse 3:

“’And will look up’, will keep watch, like Habakkuk on his watch-tower.  Have you ever found that your Father has answered a forgotten prayer?  I have, and I always feel so ashamed; it is so rude to forget.  A ‘Prayer-and-Answer Notebook’ helps one to remember.  It is evidence, which even the devil cannot dispute, of traffic with Heaven.  It kindles love; ‘I love the Lord because He hath heard’ (Ps 116.1).  How often we have had cause to say that.  My first note-book turned up among some old papers lately.  To read the notes was like finding sprays of verbena between the leaves of a book; you know how astonishingly fragrant they can be.  There was one little sentence that belonged to a rainy Sunday morning when I was, I suppose, about ten, so that leaf was about sixty years old, but it might have been only just picked, for as I read the words I remembered every detail of that prayer and that answer.

“If any of you keep such a book do not forget that the answer to many prayers is ‘Wait’, or sometimes, ‘No, not that, but something else, which, when you see Me, you will know was a far better thing.’”
