Last night I suddenly found myself thinking about certain people I haven't seen for a long time, and actually don't know all that well.  This morning I had an email to let me know one of them was seriously ill, and indeed, a message had been sent out just around the time I thought of them.  It amazes me how often (relatively speaking) this happens, but it does.  And I assume it is God at work, the Spirit giving me a nudge deep in my subconscious.  I just wish I was better at recognising these prompts when they arise rather than identifying them retrospectively!
