John 13:35

32 If God has been glorified in him, God will also glorify him in himself, and he will glorify him immediately.

33 Little 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.

34 A new commandment I give to you, that you love one another. Just as I have loved you, 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 now? I will lay down my life for you.”

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