Prior to Jesus, God demanded that people EARN their salvation. Even Jesus perform the same rituals as those before him to EARN his salvation. After Jesus left, Paul started preaching that people are not saved by works but rather by grace. Jesus must be thinking, "wish someone had told me that so I don't waste all that time with all those rituals". Now they say that Jesus' blood has washed away the sins of the world. Yet they insist the world is still full of sin. Everything about Jesus is like a world of confusion.
