Not entirely sure what your point is?
Do you mean that, if a person continues to sin that he will be judged by the Law. If so, that's wrong, for a Christian is under grace.
We will all have to keep the appointment of death. It is as if we are on death row all our lives. Then when we die, we will come before the great white judgment throne to be judged by our compliance with the Ten Commandment from our youth up.
Because non of us have been able to keep the Ten Commandment at any time, because God not only looks on the outward compliance, but on the thoughts of the heart. Even though we are converted to Christ, we still continue to break the Commandments by telling little white lies, taking that biro home from the office, saying "OMG", looking at persons with lust, wishing we could have what the Jones's have, not loving God with all our heart, soul and strength, being angry with someone without causes, and so on. Although we have forsaken the 'big' sins like habitual lying, theft, blasphemy, viewing pornography, fornication, hatred, jealousy, envy, and other works of the flesh, we will are tripped up by the "little foxes" every day, mostly without realising it. But these "iittle foxes" still come under God's strict justice, and when we stand before God in the judgment, we will be found guilty and will be subject to the same penalty as if we continued with the "big" sins.
But the difference will be that because we put our faith and trust in the finished work of Jesus on Calvary, our debt to sin has been paid by Him, and He has taken God's wrath, and the penalty for our sin on Himself. This means that when we are found guilty of sin in the judgment, we will not be sentenced to God's eternal prison without parole, and will be set free because there will be no penalty.
It is like a person standing before the court judge charged with serious crimes which brings a million dollars in fines. The judge will say, "You are guilty, but someone has come and paid the fine for you, so you can leave this court a free man".
Conversion to Christ does not magically change us into a different person on the outside. What changes in us are our hearts causing us to hate our own sinfulness, and to love holiness. This causes us to work as hard as we can with the grace and strength of the Holy Spirit to demonstrate that we are truly converted to Christ. It is not good works that will save us, but having been converted to Christ, we will demonstrate the truth of our conversion through the demonstration of a changed conduct resulting from a transformed heart.
