1. My Father is working, so I am working (16-17)
The Jews were persecuting Jesus because of the report of the invalid man. But Jesus further said the truth with courage, "My Father is working until now, and I am working." So the Jews tried to kill him because not only did he break the Sabbath but he also made himself equal with God. Jesus was not afraid of death to tell the truth. God is still working to restore the lost paradise through Jesus his Son. We too must work hard with Jesus' attitude though people may not accept our word as the Jews didn't accept Jesus' word.
2. Whoever hears my word and believes in him will live (18-30)
Here we see the importance of hearing Jesus' word. Now if the dead hear Jesus' word, they will live! They are not judged but cross over from death to life. For what Jesus says and does is exactly what God does and says. Jesus is God! Whoever does not honor Jesus, does not honor God. The time will come soon for all to come out from their graves-- those who have done what is good will rise to live, and those who have done what is evil will rise to be condemned by Jesus, the Judge.
