It’s one we don’t think about. I imagine you haven’t heard a sermon on it in a long time, if ever. It first came up in Deuteronomy and was re-emphasized a few times in the New Testament. More importantly, it has incredible potential to keep you and me out of deep messes. We can hardly imagine why it is important at all, but it got enough mileage in Scripture to show us the Lord thought it a worthy concept.
