Romans 6:1-2

What shall we say (to all this)? Should we continue in sin and practice sin as a habit so that (God’s gift of) grace may increase and overflow? Certainly not! How can we, the very ones who died to sin, continue to live in it any longer. 

Jesus died for our sins with the expectation that we would no longer continue in sin. When we are set free, we are to move forward in that freedom and not back to the practice of sin. There would be no need for salvation if we chose to remain in sin. Salvation clears the path and removes the barrier between us and God created by sin.
