Resurrection of Jesus
If Jesus is alive, He is able to give power to His followers to live a good life. The Apostle Paul taught that the believer took part in the death and resurrection of Jesus.  He said, "I am crucified with Christ, nevertheless I live, and the life I live in the flesh (body) I live by faith in the Son of God, who loved me and gave Himself for me". Epistle to the Galatians Chapter 2, verse 20
