Answer:
Law of redemption already that happened in the past
Explanation:
Christianity is a way of life which the members try to emulate the footsteps of their savior , a man known as Jesus Christ.
Talking about redemptive history is like talking about what this man came on Earth to do.
He came to redeem people if their sins and bring them back to God almighty their creator.
So the Christian Canon is redemptive history in the sense that the law in which the Christians follow, through the holy books was once a history where some one came to redeem them and set some rules to follow for Christians redemption.
