Are there different levels of Hell and different levels of pain and isolation that souls experience in Hell?

Because God is just, there will be degrees of punishment in Hell. Unsaved people—everyone whose name is not written in the Lamb's Book of Life—will be judged by God in relation to the works they have done, which have been recorded in the books of Heaven (Rev. 20:12-15). The severity of punishment will vary with the amount of truth known and the nature and number of the sins committed (Matt. 11:20-24; Luke 20:45-47, Rom. 2:3-5).
