Donating organs, it's the gift that keeps on giving, but until Ben Harper found his angel, he thought he would die.

Harper was convinced his time was up. He says "I've been on dialysis for a year and it's three hours and forty-five minutes a session, three times a week and it's not much of a life. Without a kidney donor, he'd be forced to continue treatment then possibly die.

Then he found his angel. Sherry Pridgen has been close to Ben and his family for years. She has also been an organ donor for 20 years, but when she found out about Ben’s situation, she decided to go ahead and help, instead of donating only when she dies.

Pridgen says "he was in Vietnam for two terms. A result of his kidney failure is because he was risking his life for me. So I thought, why can I not do something so simple as give him a kidney?"

So she decided to help. Sherry says "I put it in God's hands and said I'll do the part of getting the testing done and I'll take it as a sign from you that if we are a match, then that is my sign to go ahead with it.”

They matched. Ben says "an angel struck me and offered me a kidney and I love her to death.” Soon Ben and Sherry's lives will be linked forever.

They undergo surgery this Monday at 7:30am at Duke. For more information on kidney transplants go to http://www.kidney.org/
