John 13:34-38

A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. By this all will know that you are My disciples, if you have love for one another.” Simon Peter said to Him, “Lord, where are You going?” Jesus answered him, “Where I am going you cannot follow Me now, but you shall follow Me afterward.” Peter said to Him, “Lord, why can I not follow You now? I will lay down my life for Your sake.” Jesus answered him, “Will you lay down your life for My sake? Most assuredly, I say to you, the rooster shall not crow till you have denied Me three times.
