In John 20:29 (NIV), John tells his disciples, “Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.”
One thing that seems to be said by this passage is that a faith that does not require proof is a great gift. But what if there is a secondary blessing in not having tangible proof? When God touches people in tangible and measureable ways, the stories are scary. I sometimes wish I could have been there with Jacob, the Apostles, or Padre Pio, but to be there may have been too much for me.
There seems to be a horror in the Holy. Something in the Sacred can scar us. Perhaps we sinners are unfit to see or experience God as heavily as we sometimes do in this life. Maybe this is why the Saints who are closest to God so often carry symptoms which appear as misery to the world. Maybe if they have any misery left, it is not in reality a sickness or a stigmata, but complete conversion to Christ that cannot choose anything but faith and joy.
