-20 and John 15:9-17: 'Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with that person, and they with me.'; 'My command is this: love each other as I have loved you. Greater love has no one than this: to lay down one’s life for one’s friends. You are my friends if you do what I command. I no longer call you servants, because a servant does not know his master’s business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you.'
