This book is about why Christians share their faith--not because they made it up, but because God calls us to share. It explains how Lutheran beliefs, like being saved by grace alone and focusing on Jesus' sacrifice, shape the spread of the message of Jesus today. The book covers the Bible's teachings, history, modern challenges and practical ways to live out serving in God's mission today. Lutheran mission perspective may present different than that of other Christians, but all agree mission is about telling people God forgives them and invites them into His family.
