How can I prove the sheep & goat judgment occurs at the 2nd coming and is not the same as the great white throne judgment?
You can prove the Sheep and Goat judgment happens just after the 2nd Coming by looking at the reference to its timing in Matt. 25:31, “When the Son of Man comes in all his glory …” Also, in Matt 25:34 He welcomes the “sheep” (surviving Tribulation believers) into the Millennial Kingdom. The Great White Throne judgment takes place at the end of the Millennium (Rev. 20:7) and is for unbelievers only (Rev. 20:11-12).
