Thematic Bible: Those which came out of great tribulation

After these things, I looked, and there was a crowd so large that no one was able to count it! They were from every nation, tribe, people, and language. They were standing in front of the throne and the lamb and were wearing white robes, with palm branches in their hands. They cried out in a loud voice, "Salvation belongs to our God, who sits on the throne, and to the lamb!" All the angels stood around the throne and around the elders and the four living creatures. They fell on their faces in front of the throne and worshipped God, read more.
saying, "Amen! Praise, glory, wisdom, thanks, honor, power, and strength be to our God forever and ever! Amen!" "Who are these people wearing white robes," one of the elders asked me, "and where did they come from?" I told him, "Sir, you know." Then he told me, "These are the people who are coming out of the terrible suffering. They have washed their robes and made them white in the blood of the lamb. That is why: "They are in front of the throne of God and worship him night and day in his Temple. The one who sits on the throne will shelter them. They will never be hungry or thirsty again. Neither the sun nor its heat will ever beat down on them, because the lamb in the center of the throne will be their shepherd. He will lead them to springs filled with the water of life, and God will wipe every tear from their eyes."
