I give you a new commandment: love one another. As I have loved you, so you also are to love one another.
In context
32If God has been glorified in him, God will also glorify him in himself — and he will glorify him at once. 33Little children, I am with you only a little longer. You will look for me, and, as I told the Jews, so I tell you now: where I am going, you cannot come. 34I give you a new commandment: love one another. As I have loved you, so you also are to love one another. 35By this everyone will know that you are my disciples: that you have love for one another.” 36Simon Peter said to him, “Lord, where are you going?” Jesus answered, “Where I am going you cannot follow me now, but you will follow later.”
