If we take to its logical conclusion the statement that "justification by grace through faith does away with law," then there is no such thing as sin any longer, for the law defines what sin is (see also I John 3:4). If that is true, Christ died in vain.

In addition, it violently flies in the face of two clear facts: 1) Two thousand years after Christ shed His blood to pay the penalty for sin—providing the means for justification—we still must repent of sin to be forgiven. That has not changed, so sin must still exist and law still exists. Thus, the Ten Commandments still exist, as sin is the transgression of that law. How can this be if there is no law to transgress? 2) The New Testament record of Jesus Christ's and the apostles' exhortations to Christians not to sin, especially after one is forgiven.
