Today at staff meeting, we listened to a Tim Keller sermon (in the Mark series). His main point is that all love must sacrificial, hence Jesus had to die. Whether it is a parent who gives up the right to serve his/her own interests for a child or a victim who gives up the “right” to seek vengeance, love is sacrificial. He went on to talk about the fact that self-serving acts of love Carnot provide any form of happiness or joy.
One quote grabbed my attention. He quoted the first Harry Potter book regarding the tremendous power of sacrificial love to show that even those who are not believers are moved by sacrificial love.
Dumbledore speaking to Harry:Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. He didn’t realize that love as powerful as your mother’s for you leaves a mark. Not a scar, no visible sign [but]…to have been loved so deeply, even though the person who loved us is gone, will give us some protection forever.

What was the name of the sermon? Great idea for a staff meeting.
