The new covenant is that we are no longer under the law. And the we are children of God. And free from sin. The devil no longer has the keys to heaven and hell, Jesus has them. If your works are not of God, then you will be judged. According to our works we will be judged. You get saved, don't mean you can do the works of the devil. It means your sins are forgiven. Our sins are forgiven, yesterday, today and tomorrow. But you have to repent and do good works. Death is cast into hell.
