What Jesus actually says is this ~ “Look! I stand at the door and knock. If you hear my voice and open the door, I will come in, and we will share a meal together as friends."
JOhn 13.15 & 34
IN John 13.15 Jesus is saying "For I gave you an example, so that you also would do just as I did for you." And then later in the chapter he makes it even clearer... verse 34 "I am giving you a new commandment, that you love one another; just as I have loved you, that you also love one another."
Over the years, judging by our TV rhetoric - we seem to think Jesus said something quite different.
