You seem like you're almost getting it now. If someone is judged by the 10 commandments then they'll be judged by their failure to keep them.
Are you postulating that believers in Christ will be judged for their sins? Not what my Bible says. We cannot be saved by keeping the 10 commandments:
Galatians 3:24-28
24Wherefore the law was our schoolmaster
to bring us unto Christ, that we might be justified by faith.
25But after that faith is come, we are no longer under a schoolmaster.
26For ye are all the children of God by faith in Christ Jesus.
27For as many of you as have been baptized into Christ have put on Christ.
28There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
29And if ye
be Christ's, then are ye Abraham's seed, and heirs according to the promise.
Romans 3:20-26
20Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law
is the knowledge of sin.
21But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
22Even the righteousness of God
which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
23For all have sinned, and come short of the glory of God;
24Being justified freely by his grace through the redemption that is in Christ Jesus:
25Whom God hath set forth
to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
26To declare,
I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
I also never said "don't keep the 10 commandments." You projected that assumption into what I've said.
Don't take my word for it. Read the Bible and come to your own conclusion.
Again, if we love God and love our neighbor we'll follow His commandments, but again, we aren't justified by law keeping as you seem to be suggesting. We are justified by Christ.
