John 13:33-36 NIV
“My children, I will be with you only a little longer. You will look for me, and just as I told the Jews, so I tell you now: Where I am going, you cannot come.
“A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.”
Simon Peter asked him, “Lord, where are you going?”
Jesus replied, “Where I am going, you cannot follow now, but you will follow later.”
