John 5: 17-29, The Son Will Raise the Dead

Jesus has been accused of healing on the Sabbath and of claiming to be equal to God.  The disciple John then records a lengthy response to these accusations.

John 5: 17-19, My Father and I are working
In his defense Jesus said to them, “My Father is always at his work to this very day, and I too am working.” 
18 For this reason they tried all the more to kill him; not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God.

Jesus identifies his work with that of the Father (God) and this claim intensifies the anger of the Jewish leaders.

John 5: 19-23, The Son reflects all of God.
Jesus gave them this answer: “Very truly I tell you, the Son can do nothing by himself; he can do only what he sees his Father doing, because whatever the Father does the Son also does. 
20 For the Father loves the Son and shows him all he does. Yes, and he will show him even greater works than these, so that you will be amazed. 
21 For just as the Father raises the dead and gives them life, even so the Son gives life to whom he is pleased to give it. 
22 Moreover, the Father judges no one, but has entrusted all judgment to the Son, 
23 that all may honor the Son just as they honor the Father. Whoever does not honor the Son does not honor the Father, who sent him.

Jesus calls himself "the Son", a Messianic term, and continues to identify his work as God's work... and identifies God's work as his.  In this relationship is love and support.  One of the activities of the Son will be to raise the dead and apparently to judge mankind.

Jesus claims to be, in some sense, co-equal with God. This claim is, of course, blasphemy.  Unless it is true.

John 5: 24-29, The Son will raise the dead
“Very truly I tell you, whoever hears my word and believes him who sent me has eternal life and will not be judged but has crossed over from death to life. 
25 Very truly I tell you, a time is coming and has now come when the dead will hear the voice of the Son of God and those who hear will live. 
26 For as the Father has life in himself, so he has granted the Son also to have life in himself. 
27 And he has given him authority to judge because he is the Son of Man.

28 “Do not be amazed at this, for a time is coming when all who are in their graves will hear his voice 29 and come out—those who have done what is good will rise to live, and those who have done what is evil will rise to be condemned. 

The write of the gospel has Jesus explaining eternal life as hearing the voice of Jesus and believing him.  That act gives eternal life, "crossing over" from death. The Messiah has God-given authority to judge the world.  Not just those in Jesus audience have this opportunity; eternal life (and judgement) extend to those in the grave.
