Not the law of Moses.
John 1:17 For the law was given by Moses, but grace and truth came by Jesus Christ.
1 John 2
7 Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning.
8 Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.
9 He that saith he is in the light, and hateth his brother, is in darkness even until now.
10 He that loveth his brother abideth in the light, and there is none occasion of stumbling in him.
11 But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.
John 13:34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
John 13:35 By this shall all men know that ye are my disciples, if ye have love one to another.
John 15:12 This is my commandment, That ye love one another, as I have loved you.
John 15:17 These things I command you, that ye love one another.
