Would think this would be similar to Lazarus; a sort of partial resurrection / re-animation of the person's earthly body & spirit, but not a complete full redeemed resurrection as we will experience after the second coming of Christ. Since they are not mentioned again in the New Testament, maybe they did not stick around raised from the dead very long; but what a display of God's awesome redeeming power!
I wonder if their experience is maybe similar to some of those people who experience near-death or actual-death experiences, but become alive again after an encounter with God / heaven... Would be intriguing to read an account of one of the NT people who were raised from the dead. Cool novel premise?
