In John 5:25-29 we read:
“Truly, truly, I say to you, an hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live. For as the Father has life in himself, so he has granted the Son also to have life in himself. And he has given him authority to execute judgment, because he is the Son of Man. Do not marvel at this, for an hour is coming when all who are in the tombs will hear his voice and come out, those who have done good to the resurrection of life, and those who have done evil to the resurrection of judgment.
(John 5:25-29 ESV emphasis mine)
Are these intended to refer the same "hour" or are they two different hours? My inclination is to see them as two distinct hours, but at the same time the language is so similar I'm not sure.
