The promise to the white robed ones before the throne describes the great ordeal our faith forebears suffered. Indeed, when we make this portion of the letter a prophecy of the imagined future we dishonor the real people who went without food and water as they suffered the scorching sun and the heat of the day. They were mostly slaves and women, the least and the left behind, which is why using the testimony of their tribulation in best-selling books and cheesy DVDs by the rich and powerful insults the real people to whom these words were written. Their tears will be wiped away and though we might have much to make us weep the great multitude that came out of the great ordeal does not include us. It is not to say we are left out because we happen to live in a time when the empire embraces the church without trying to strangle it. It just means we can't read about those persecuted and ultimately killed for the faith and make it about us. What is about us, persecuted or not, is that the Lamb at the center of the throne is the Shepherd of every nation and tribe and people and language which means leaving anyone behind is the last thing on the Lord's mind.
