The concept of "luck" or "chance" is mentioned very rarely in the Bible. In the RSV, I find only
Do not reveal your thoughts to every one, lest you drive away your good luck (Sir 8:19)
I tried looking up good fortune and surprise and fate only found uses that don't mean
1. The chance happening of fortunate or adverse events; fortune
2. Good fortune or prosperity; success
3. One's personal fate or lot
If you google "make your own luck" you will find lots of validation that you can make your own luck, find the things you need, meet the people you want, arrive at the place you can prosper. Some point to preparedness and planning; others veer off into occult practice.
I have long been "lucky" in two superficial aspects of life: I can always get a great parking space, and I tend to do well at games of chance, especially when I don't care (which means without any real money on the line - think "Las Vegas Night").
And I delighted in the concept of serendipity, when I would run across an old friend when I made a wrong turn, or found a book I've hunted for years when I went into an old store to please a traveling companion.
Well, it's probably abundantly clear to all you better-Christians-than-me out there, but it truly didn't occur to me until the last few years that there is no luck, there is only blessing. Even when I truly understood that my joy is in Jesus Christ alone, I still drew a line above a certain amount of luck: how could God be concerned with my strategy for Yahtzee?
It's sinking in, that God loves me so much, and is so close to me, that He puts His Father's hand into my life and directs it gently for my good. To that end, as a witness, I'm trying to unlearn the phrase "What luck!" and replace it with "What a blessing!"
On a side note, what's your luck/blessing? I can find a parking place in front of Indianapolis Motor Speedway on Memorial Day....
