How Christianity Grew from a Dozen Disciples to a Worldwide Movement At the beginning of the first century, a teacher named Jesus of Nazareth shook Roman-occupied Israel with his preaching and teaching. When, several years later, the Romans crucified Jesus and sealed him in a tomb, his disciples were crushed and confused.Two thousand years later, more than two billion followers of Jesus can be found around the globe. Justin Gatlin tells the story of how that happened-from the miraculous resurrection of Jesus to the spread of Christianity throughout Africa and Asia in the twentieth and twenty-first centuries. For each era covered in A Brief Walk through Christian History, Justin shows how Christians from that time periodresponded to Christ’s call to spread the gospel message, described and defined what it means to be a follower of Christtaught and discipled people who joined the church.It is an amazing story-one in which you can see the hand of God in the growth and expansion of the church.
