"This is my commandment, that you love one another as I have loved you.
No one has greater love than this, to lay down one's life for one's friends.
You are my friends if you do what I command you.
I do not call you servants any longer, because the servant does not know what the master is doing; but I have called you friends, because I have made known to you everything that I have heard from my Father.
References for John 15:15
You did not choose me but I chose you. And I appointed you to go and bear fruit, fruit that will last, so that the Father will give you whatever you ask him in my name.
I am giving you these commands so that you may love one another.
