You don't need veils or dark glasses. You can see the glory of God by faith, and seeing you will believe, and believing you will live. This light that we see, this glory, exists in the midst of darkness. It was a bitter march to Mount Sinai, and it was a frustrating sight that greeted Moses when he first descended. It was a stern lecture about Jesus' death that preceded the walk up the Mount of Transfiguration, and a frustrating scene that greeted Jesus when he descended.
Darkness is all about.
That is what makes the Glory of God so bright. And the darkness has not overcome it. For all of God's glory, for all the mountaintop experiences, it is not obvious that darkness will be overcome, not in your life, not in mine, not in anyone's. Too often this question is left out by the presiding pastors. The day will end as it always does with Tinkerbell lifted up in a display of fireworks.
