The purpose of the signs of Jesus in the book of John is that we might believe, that we might have life. Not that we might raise from the dead, but that we might have life in the name of Jesus. 

There are two reasons this is important to remember. 1) If resurrection is our hope then we have to wait until after we die to experience it, but the hope of life in Jesus begins now. 2) Resurrection isn’t always even good news. According to this passage some will be resurrected not to life, but to judgment. For those, the prospect of resurrection is not a hopeful or comforting thought. Those who die without following Jesus will resurrect to an eternity of separation from Jesus an eternity utterly separated from love and goodness. All that to say, resurrection isn’t our hope, life is.
