When Jesus says that those who obey won’t die, he is talking about spiritual death, not physical death. Even physical death will eventually be overcome. Those who follow Jesus will be raised to live eternally with him.
The great “I am” statement is one of the most powerful statements uttered by Jesus. When he said that he existed before Abraham was born, he was undeniably proclaiming his divinity. Not only did Jesus say that he existed before Abraham, but he also applied God’s holy name to him self. This claim demands a response. It cannot be ignored. The Jewish leaders tried to stone Jesus for blasphemy because he exclaimed equality with God. But Jesus is God.
