“To preach Christianity meant (to the Apostles) primarily to preach the Resurrection. … The Resurrection is the central theme in every Christian sermon reported in the Acts. The Resurrection, and its consequesnces, were the ‘gospel’ or good news which the Christians brought.” CS Lewis in Miracles
The central theme of Christianity is not about what Christians do, but about what God has done for Christians in raising Jesus from the dead. This is very important. Many Christians and people who know a little about Christianity think that the story is about us and how good we are. People think that it’s about being the best person you can be, but it’s NOT! The central theme of the Christian message has nothing to do with what WE do, but everything with what GOD does. It’s all about JESUS!
