So the cross not only brings Christ's life to an end, it ends also the first life, the old life, of every one of His true followers. It destroys the old pattern, the Adam pattern, in the believer's life, and brings it to an end. Then the God who raised Christ from the dead raises the believer and a new life begins.
Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come! 2 Corinthians 5:17
