Romans 7:4, 6

In the same way, my brothers and sisters, your old selves died, and you became free from the law through the body of Christ. This happened so that you might belong to someone else—the One who was raised from the dead—and so that we might be used in service to God.

In the past, the law held us like prisoners, but our old selves died, and we were made free from the law. So now we serve God in a new way with the Spirit, and not in the old way with written rules.
