John 15:11-14 (KJV) 

¹¹ These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.

¹² This is my commandment, That ye love one another, as I have loved you.

¹³ Greater love hath no man than this, that a man lay down his life for his friends.

¹⁴ Ye are my friends, if ye do whatsoever I command you.
