How did Jesus Defeat Sin & Evil? Jesus' Life Jesus lived on Earth for about 33 years. All of those years he was helping others, striving for goodness and defeating sin and evil. Mainly the devil. During Jesus' life he overcame many obstacles some of which involved evil spirits and were led by the devil. These evil spirits were defeated when Jesus commanded them to "go". This shows that Jesus will always overcome sin and evil.
Jesus' Death Without Jesus' death on the cross for our sins, nobody would have internal life. Jesus came and died to become the final and perfect sacrifice for our sins. Through him, the promise of internal life becomes effective through faith and those who believe in Jesus. It is thought that this has defeated sin and evil, mainly overpowering the devil. This is because the devil wanted all those that had done wrong to be brought to hell and not have internal life.
Jesus' Resurrection Jesus' resurrection was a massive surprise to evil. They thought that they had destroyed their only threat to their power, but they hadn't. By rising from the dead it showed the devil that Jesus was almost unstoppable. This also makes the devil powerless to Jesus so he can go on and complete his mission.
