John 13:36-38   New International Version    

36 Simon Peter asked him, “Lord, where are you going?”

Jesus replied, “Where I am going, you cannot follow now, but you will follow later.”

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

38 Then Jesus answered, “Will you really lay down your life for me? Very truly I tell you, before the rooster crows, you will disown me three times!
