In John 15:12-17 Jesus called his disciples to be identified by the badge of love. In doing so, He elevated his disciples from the status of servants to friends, gave them explicit instructions as to their responsibility to love each other and then set the highest standard possible by speaking of love as sacrifice. We often remember his words in John 15:13 when we remember our war dead, but these words were not given just to write on a tombstone. Instead they are to be lived out in the world.
