Where is the great tribulation found in the bible?
"For then there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will." (Matthew 24:21) Note that Jesus says it had not yet begun, would be worse than anything that happened previously, and nothing that followed would be worse.
After these things I looked, and behold, a great multitude which no one could count, from every nation and all tribes and peoples and tongues, standing before the throne and before the Lamb, clothed in white robes, and palm branches were in their hands; and they cry out with a loud voice, saying, "Salvation to our God who sits on the throne, and to the Lamb." And all the angels were standing around the throne and around the elders and the four living creatures; and they fell on their faces before the throne and worshiped God, saying, "Amen, blessing and glory and wisdom and thanksgiving and honor and power and might, be to our God forever and ever. Amen." Then one of the elders answered, saying to me, "These who are clothed in the white robes, who are they, and where have they come from?" I said to him, "My lord, you know." And he said to me, "These are the ones who come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb. (Revelation 7:9-14)
Darby created that theory (i think)
Uhhhh... Darby didn't write the Gospel of Matthew and book of Revelation, did he? Not an expert on Darby by any stretch of the imagination, but I am fairly certain that even his most rabid supporters don't believe he wrote any of the books of the Bible lol.
Not sure how that Scripture relates to what is being discussed... could you please explain?
