There have been lots of wonderful answers to prayer over many years, including recently. One I remember was as a 15-year-old sitting in chapel with the prospect of three frightening tests that day, for which I had done no preparation, and praying that if I got through it then I would do anything for God. I did get through and did nothing about it, except forget about God.
Another was praying about whether I should ask my future wife to marry me: I was sitting alone by a canal in Holland. I felt I should, did, and she said yes. It was a wonderful decision.
The most recent was when I was going to see some incredible work done by a group of young women helping trafficked sex workers. I prayed that I could find, in my complete bafflement, something hopeful and good to say to the young women with whom they worked.
