K018. Jesus said that He did not come to destroy the law, or the prophets

Mat 5:16-20 KJV  Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.  (17)  Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.  (18)  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.  (19)  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.  (20)  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.

But many think that Jesus came to fulfil the law so that we do not have to keep any law. Yes, and no.
Yes, He fulfilled only the law concerning about Himself; but not all the laws or commandments that we still need to keep. I have said earlier that there are two main types of the laws given by God or Moses:

1. The law concerning Christ (The circumcision and ceremonial law)
Luk 24:26-48 KJV  Ought not Christ to have suffered these things, and to enter into his glory?  (27)  And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself ..  (44) And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.  (45)  Then opened he their understanding, that they might understand the scriptures, ..  (47)  And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.  (48)  And ye are witnesses of these things.

2. and the law concerning God's will for us (God's commandments in the scripture, the law and the prophet, and the law of Christ)
Mat 7:15-25 KJV  Beware of false prophets, which come to you in sheep's clothing, .. (20)  Wherefore by their fruits ye shall know them.  (21)  Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.  (22)  Many will say to me in that day, Lord, Lord, ..
Luk 24:26-48 KJV ... (47)  And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.  (48)  And ye are witnesses of these things.

Please think, If Jesus would still give us the law or command to do something, don't you think that He has the doctrine for us too. If He has the doctrine for us, He would never tell us that He keep all the laws and commandments for us so that we have no more law to keep:
Mat 28:19-20 KJV  Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:  (20)  Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Joh 7:16-18 KJV  Jesus answered them, and said, My doctrine is not mine, but his that sent me.  (17)  If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.  (18)  He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him.
