The only One who can add or remove law is [The Word of] God.
The addition of this commandment does not
negate our responsibility to follow the plethora of others the Most High God had already set up.
Matt 5:17-20:
Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
In order to exceed the righteousness of the scribes and Pharisees, you need to follow and know the Law perfectly,
and you need to actually love God (which means there is no status or award expected when following the laws of God because you do that for people/Parents you love.)
Now, consider this - John 14:15-20:
If ye love me, keep my commandments.
And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
I will not leave you comfortless: I will come to you.
Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
At that day ye shall know that I am in my Father, and ye in me, and I in you.
He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
[emphasis mine]
He tells us that if we love Him, we will KEEP the commandments The Literal, Living Word of God gave since the foundations. The Most High God - the Father told us:
Now, Jeremiah 31:31-34:
Behold, the days come, saith the Lord, that I will make a
new covenant with the house of Israel, and with the house of Judah:
Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
A
nd they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more.
No one needs any construction of man to know God. He promised us so much - including that His Word will be written on our hearts!
That is good news - that you can be a
dullard, and He will still consider you so that you will know Him.
