John 15:13

Amplified Bible

¹³No one has greater love [nor stronger commitment] than to lay down his own life for his friends.

Mark 12:31

Amplified Bible

³¹This is the second: ‘You shall [unselfishly] ^[a]love your neighbor as yourself.’ There is no other commandment greater than these.”^(A)

Mark 12:31 The key to understanding this and other statements about love is to know that this love (the Greek word agape) is not so much a matter of emotion as it is of doing things for the benefit of another person, that is, having an unselfish concern for another and a willingness to seek the best for another.
