Sister Rose is simply stating the Gospel message [Love one another as I have loved you] in a modern form.  If we disregard the message of love from Christ, 'thinking that its not going to benefit the country in any way,' we have learned NOTHING from Jesus.
  

We learned from Christ that:
a) With God's life in us, we CAN overcome prejudices, promote reconciliation, foster unity in diversity, and work for justice and peace
b) Love lets us find joy in the midst of suffering and pain.  Christ did not end human suffering; instead, he showed how suffering for those we love/care about can bring new life to them
c) Jesus promised that he will never leave us orphaned [Jn 14:18], so we are to proceed with courage.
