John 13:35

33Little children, I will be with you a little while longer. You will seek me, and as I said to the Jews, ‘Where I am going, you can’t come,’ so now I tell you.

34A new commandment I give to you, that you love one another. Just as I have loved you, you also love one another.

35By this everyone will know that you are my disciples, if you have love for one another.”

36Simon Peter said to him, “Lord, where are you going?” Jesus answered, “Where I am going, you can’t follow now, but you will follow afterwards.”

37Peter said to him, “Lord, why can’t I follow you now? I will lay down my life for you.”
