There are different theories on how to interpret the images in Revelation where God’s wrath will be poured out at the end of time. “The Great Tribulation” is the source of heated argument among some Christians.
Whatever your view, we can be certain Jesus will return and will return in glory. And not only will God rescue us at the end of time, but He can, and does, rescue us now from whatever our present “tribulations” may be.
