John 13:33-38

Little children, I am with you [only] a little longer. You will look for Me and, as I told the Jews, so I tell you now, ‘Where I am going, you are not able to come.’ [John 8:21] I am giving you a new commandment, that you love one another. Just as I have loved you, so you too are to love one another. By this everyone will know that you are My disciples, if you have love and unselfish concern for one another.” Simon Peter said to Him, “Lord, where are You going?” Jesus answered, “Where I am going, you cannot follow Me now; but you will be able to follow later.” Peter said to Him, “Lord, why cannot I follow You now? I will lay down my life for You!” [Matt 26:33-35; Mark 14:29-31; Luke 22:33, 34] Jesus answered,“Will you [really] lay down your life for Me? I assure you and most solemnly say to you, before a rooster crows you will deny and completely disown Me three times.
