John 13:35

31 When Judas had gone out, Jesus said, “Now the Son of Man is glorified, and God is glorified in Him.

32 If God is glorified in Him, God will also glorify the Son in Himself—and will glorify Him at once.

33 Little children, I am with you only a little while longer. You will look for Me, and as I said to the Jews, so now I say to you: ‘Where I am going, you cannot come.’

34 A new commandment I give you: Love one another. As I have loved you, so you also must love one another.

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

36 “Lord, where are You going?” Simon Peter asked. Jesus answered, “Where I am going, you cannot follow Me now, but you will follow later.”

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

38 “Will you lay down your life for Me?” Jesus replied. “Truly, truly, I tell you, before the rooster crows, you will deny Me three times.
