The lot is cast into the lap, but the response is from the Lord. –Proverbs 16:33
There is a mentality today that casting lots is superstitious at best and magic from the pits of Hell at worst.
We must remember, though, that many people throughout the Bible cast lots, most recently in Acts chapter one with the choosing of Matthias to replace Judas Iscariot as an Apostle. Perhaps you have even drawn straws, which is very similar.
Most frequently today lots is seen as a game, whether for children or when gambling, like the lottery (guess where the name comes from). It is seen as something you wish for luck in.
But luck has nothing to do it.
God is in control. Lots can be used when you are really struggling with a decision (like which job offer to accept) or if you are simply feeling apathetic about a choice (like maybe where to eat out or what movie to watch … if you are into that kind of thing).
The key is to remember that you are asking God for direction. Otherwise, you are merely being superstitious.
