Re'na Garcia is a 24-year-old wife and mother of two preschoolers and a full-time nanny for two other children. She leads a busy life, but her favorite part of the day is when she goes out to RAOK somebody's world—as in performing "Random Acts of Kindness."

She and her husband, Aaron, are part of a growing network of Christians who seek to anonymously bless other people in the name of Jesus. They have even started a website to help share ideas, www.raoked.com. Some of those ideas include:

• Leaving a roll of quarters at the laundromat
• Paying for the person behind you at a drive-thru
• Leaving grocery gift cards in mailboxes
• Paying rent for a family in need
• Handing out water or sports drinks on a biking trail.

Garcia also hands out a RAOK business card that explains her motivation, information about her church, and that there are no strings attached. "People were drawn to Christ not because he stood on a mountain and preached," she says, "but because he filled their needs."
