I would agree to a point. By the time of Christ Judaism had lost the meaning of what had been written in scripture. They had elevated the physical act of conforming to the commandments as the utmost priority. Thus a truly reprehensible person inwardly could continue to appear holy and righteous outwardly.
Mat 23:27 Woe unto you, scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead [men's] bones, and of all uncleanness.
Mat 23:28 Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.
What the scribes and Pharisees didn't understand was that a change of heart is what would transform them and conform their life to the ten commandments. The purpose of the written commandments is to show us where we are deficient in our spiritual character.
So the laws that are put into our hearts and minds seem to be the ten commandments. Or rather, the spiritual equivalent of the written law, love for God and others. Here's why I say that:
2Cr 3:3 clearly you are an epistle of Christ, ministered by us, written not with ink but by the Spirit of the living God, not on tablets of stone but on tablets of flesh, that is, of the heart.
Above Paul compares the old tablets of stone (the written ten commandments) to what is written in our hearts.
It's also why Christ says:
Mat 22:37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
Mat 22:38 This is the first and great commandment.
Mat 22:39 And the second [is] like unto it, Thou shalt love thy neighbour as thyself.
Mat 22:40 On these two commandments hang all the law and the prophets.
If we love God with all our heart and soul and mind, and others as ourselves then our outward appearance AND our inward state will be the same. We won't be like a clean tomb on the outside but full of lawlessness on the inside.
Note that the above commandments were prior to the New Commandment in John 13:34. 1 John 3:23 says, "THIS is His commandment, that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment."
We are free from the law, and the above commandments were the foundation of that law. We now have commandments that raise the standards. We now are expected to love as Christ loved, not as we love ourselves. IF you find the license to sin in this, then you're reading with your flesh.
