Greg Laurie is both a pastor and an evangelist. His giftedness in sharing the gospel is obvious. More than 6 million have attended his Harvest Crusades, and more than 500,000 have registered decisions of faith. So he helps us consider a few things about sharing our faith. We have a life-saving message, and we just can't keep that to ourselves. Those who do share it experience a thrilling sense of satisfaction like no other.
