Thinking of the Bible as shifting and moving may feel spiritually risky, bordering on heretical, but it isn't. Sermons, Bible study materials, prayer books, and the like adapt the ancient words for modern benefit all the time. Biblical psalms that praise the Lord and then ask God to squash the enemy are often edited for church consumption. Generally speaking, Christians think asking God to kill their enemies is wrong (Jesus said so), so adjustments are made to those parts of the Bible that say exactly that. Laws that assume the legitimacy of slavery or virgins as their fathers' property are omitted or given a more spiritual spin. The list goes on.
