John 13:33-35

33Children, I am still with you for a little while. You will look for me, and just as I said to the Jewish religious leaders, ‘Where I am going you cannot come,’ now I tell you the same.

34“I give you a new commandment – to love one another. Just as I have loved you, you also are to love one another.

35Everyone will know by this that you are my disciples – if you have love for one another.”
