After the invalid was healed (Jn. 5:1-9a), things went bad because Jesus healed on the Sabbath. The Jewish leaders were outraged because it was a day of rest. Jesus explained that God was still working to give life & judge as babies were born & people died. God didn’t take a day off one day a week. If he did, life would collapse.
Jesus explained that as his Father still worked to give life to people, he likewise worked to give people life. That threw gasoline onto the fire, & the Jews accused Jesus of blasphemy: making himself equal with God. So Jesus began to graciously show them how he was working with God by giving life and judging as only God could. With that having been said, Jesus told people that to have eternal life they were to believe in him. Jesus is still working the works of God today to bring eternal life to all people, and he asks us to work together with him.
