I am presently wrapping up a residency week of studying the Old Testament at Covenant Theological Seminary. I’ve got to admit that the class is messing with a lot of my theological categories. We just finished having a discussion on the casting of lots that is a very prominent method used throughout the Old Testament and was even used for the selection of an apostle in the days of the early church (Acts 1:26). My conclusion is that, as long as it is used with caution, there may be circumstances in which is it appropriate to cast lots for making a decision.
Below is a video of John Piper discussing the issue of casting lots. Appropriately, he emphasizes the need for using caution.
