The Bible is grounded in reality. It recognizes that the world is not what it should be, and it helps us to understand why that is. The Bible also tells us about God's plan to redeem and restore creation through the saving work of Christ. Deuteronomy 21 is a chapter aimed at teaching Israel how to handle certain situations where the corruption of sin is seen, but it also points us forward to Jesus Christ, who tells us he is making all things new.
