John 1, 26

but there is one among you whom you do not recognize

John 13, 34-35

I give you a new commandment: love one another. As I have loved you, so you also should love one another. This is how all will know that you are my disciples, if you have love for one another."

John 15, 12-17

This is my commandment: love one another as I love you. No one has greater love than this, to lay down one's life for one's friends. You are my friends if you do what I command you. I no longer call you slaves, because a slave does not know what his master is doing. I have called you friends, because I have told you everything I have heard from my Father. It was not you who chose me, but I who chose you and appointed you to go and bear fruit that will remain, so that whatever you ask the Father in my name he may give you. This I command you: love one another.
