I read John Piper's blog. I was intrigued when I read this:
"Rachel Barkey is a 37 year-old wife and mother of two who is dying of cancer. She only has weeks to live. On March 4, she addressed 600 women and in 55 minutes delivered one of the most God-centered, gospel-soaked, honest, moving, and beautiful messages I have heard. I don't know that Rachel has read John's article, Don't Waste Your Cancer, but she is a beautiful example of every point John made.
Check out Rachel's website where you can watch or download the video and audio. You will not regret the 55 minutes. Very little is more important than the things she says."
I just listened to it. Her message is one of the most moving, convicting, encouraging, beautiful things I have ever heard. Please, please, take an hour and listen to what she has to say.
