God can change Laws, and has, any time HE wants. Jehovah/YHVH God foretold that He would change the Mosaic Law, through a "prophet like Moses".
Deut 18:15-19 Jehovah thy God will raise up unto thee a prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken; 16 according to all that thou desiredst of Jehovah thy God in Horeb in the day of the assembly, saying, Let me not hear again the voice of Jehovah my God, neither let me see this great fire any more, that I die not. 17 And Jehovah said unto me, They have well said that which they have spoken. 18 I will raise them up a prophet from among their brethren, like unto thee; and I will put My words in his mouth, and he shall speak unto them all that I shall command him. 19 And it shall come to pass, that whosoever will not hearken unto My words which he shall speak in My name, I will require it of him.
Acts 3:19-24 Repent ye therefore, and turn again, that your sins may be blotted out, that so there may come seasons of refreshing from the presence of the Lord; 20 and that he may send the Christ who hath been appointed for you, (even) Jesus: 21 whom the heaven must receive until the times of restoration of all things, whereof God spake by the mouth of His holy prophets that have been from of old. 22 Moses indeed said, A prophet shall the Lord God raise up unto you from among your brethren, like unto me. To him shall ye hearken in all things whatsoever he shall speak unto you.
23 And it shall be, that every soul that shall not hearken to that prophet, shall be utterly destroyed from among the people. 24 Yea and all the prophets from Samuel and them that followed after, as many as have spoken, they also told of these days.
John 1:45 Philip findeth Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph.
John 12:49-50 For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak. 50 And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.
John 14:24 He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.
