John 13:33-38

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

34 A new commandment I give to you, that you love one another, just like I have loved you; that you also love one another.

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

36 Simon 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."

37 Peter said to him, "Lord, why can't I follow you even now? I will lay down my life for you."

38 Jesus answered him, "Will you lay down your life for me? Most assuredly I tell you, the rooster won't crow until you have denied me three times.
