This is a historical look at the first 100 years of the Christian Church on earth. It shows how improbable the rise of Christianity was when looked at from a human perspective. Nothing in the human experience would support this outcome given the circumstances in which it occurred. Many of us believe that humans are the highest forms of life, that there are no "supernatural" beings. Buy God does exist, but so does Satan. The result is a cosmic battle between good and evil that shapes our daily lives. Free will allows us to sin even after becoming Christians. Human conflicts are not merely personto person, or nation to nation, but fundamentally a battle between good and evil, between God and Satan. All evil comes from Satan while only good comes from God. Jesus' crucifixion apparently eliminated his threat to Satan thought but the resurrection showed how wrong that was. Game on making the first 100 years a critical time in a cosmic battle between good and evil. The first century success of Christianity was a great Christian achievement. This book provides the historical context which demonstrates that God working through humans enabled the birth of Christianity in the 1st century AD. The eleven remaining leader less disciples were fearful for their lives and ill equipped to spread gospel. Their success was truly an act of God's, a first battle in the ongoing war between good and evil which continues to this day. An epilog details how Christianity reached maturity in subsequent centuries.
