And he moaned again: "Oh, Lord, have mercy. Have mercy, Lord."
There came to him again the communion service at which Elisha had knelt at his father's feet. Now this service was in a great, high room, a room made golden by the light of the sun; and the room was filled with a multitude of people, all in long, white robes, the women with covered heads. They sat at a long, bare, wooden table. They broke at this table flat, unsalted bread, which was the body of the Lord, and drank from a heavy silver cup the scarlet wine of His blood. Then he saw that they were barefoot, and that their feet were stained with this same blood. And a sound of weeping filled the room as they broke the bread and drank the wine.
Then they rose, to come together over a great basin filled with water. And they divided into four groups, two of women and two of men; and they began, woman before woman and man before man, to wash each other's feet. But the blood would not wash off; many washings only turned the crystal water red; and someone cried: "Have you been to the river?"
Then John saw the river, and the multitude was there. And now they had undergone a change; their robes were ragged, and stained with the road they had traveled, and stained with unholy blood; the robes of some barely covered their nakedness; and some indeed were naked. And some stumbled on the smooth stones at the river's edge, for they were blind; and some crawled with a terrible wailing, for they were lame; some did not cease to pluck at their flesh, which was rotten with running sores. All struggled to get to the river, in a dreadful hardness of heart: the strong struck down the weak, the ragged spat on the naked, the naked cursed the blind, the blin crawled over the lame. And someone cried: "Sinner, do you love my Lord?"
Then John saw the Lord--for a moment only; and the darkness, for a moment only, was filled with a light he could not bear. Then, in a moment, he was set free; his tears sprang as from a fountain; his heart, like a fountain of waters, burst. Then he cried: "Oh, blessed Jesus! Oh, Lord Jesus! Take me through!"
Of tears there was, yes, a very fountain--springing from a depth never sounded before, from depths John had not known were in him. And he wanted to rise up, singing, singing in that great morning, the morning of his new life. Ah, how his hears ran down, how they blessed his soul!--as he felt himself, out of the darkness, and the fire, and the terrors of death, rising upward to meet the saints.
John is horrified by the vision of the armies of darkness, but knows he has to go through. Paralyzed by fear, he watches them take communion and be washed in the river, a commonly used metaphor for the cleansing power of the Crucifixion. He sees their need for cleansing, and has already been brought to the place where he knows his own need of it too. This is sufficient to break through his fear and to get him to see the Lord, and to be saved. Through Christ's help, he "goes through." He is saved.
