It's pretty simple

"No, you're still judged by the law. Luke 10:26 and Luke 18:20."

You don't include the quotes, so I will.

Luke 10:26-28 And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life? He said unto him, What is written in the law? how readest thou? And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. And he said unto him, Thou hast answered right: this do, and thou shalt live.

and

Luke 18:18-22  And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life? And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God. Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother. And he said, All these have I kept from my youth up. Now when Jesus heard these things, he said unto him, Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me.

Not one single inference about judgment in either passage.  Neither god nor Jesus judges anyone.  You only judge yourself.  Judgment will be you, judging you.  It's pretty simple.

John 5:22  For the Father judgeth no man, but hath committed all judgment unto the Son: 

John 8:15  Ye judge after the flesh; I judge no man.

Each person on the planet is a mirror image of you (we are each created in god's image).  Each time you judge someone, you are judging yourself.  When you can learn to stop judging yourself, you will stop judging others.  Only humans judge.

Matthew 7:1-5 "Judge not, that you be not judged. For with what judgment you judge, you will be judged; and with the measure you use, it will be measured back to you. And why do you look at the speck in your brother’s eye, but do not consider the plank in your own eye? Or how can you say to your brother, ‘Let me remove the speck from your eye’; and look, a plank is in your own eye? Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck from your brother’s eye. 

By the way, if you follow the law to the letter as the "certain ruler" had done, then - per Jesus, you must sell all of your possessions and give the proceeds to the poor, in order to follow him.  How many people do that!
