John 13:33-38

33 Dear children, I am still with you a little longer. You will seek me, but, as I said to the Jews, `Where I am going you cannot come,' so for the present I say to you.

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

35 It is by this that every one will know that you are my disciples--if you love one another."

36 "Master," inquired Simon Peter, "where are you going?" "Where I am going," replied Jesus, "you cannot be my follower now, but you shall be later."

37 "Master," asked Peter again, "why cannot I follow you now? I will lay down my life on your behalf.

38 "You say you will lay down your life on my behalf!" said Jesus; "in most solemn truth I tell you that the cock will not crow before you have three times disowned me."
