Before Christ, your identity was in Adam, and the bloodline of Adam is deserving of spiritual death because of sin. The Bible says that one man's trespass brought condemnation to all men in Adam. By one man's disobedience, many were made sinners and by one man's obedience, the many will be made righteous. We deserve death but because of Christ, we’re now a new creation. If you're not living a victorious Christian life it may be because you don't believe your identity has changed.
