We know the time is short, but we don't know how short. It is very likely that each of us knows someone who will be involved in the judgments of the tribulation period. The following is a summary of the judgments that will occur during the tribulation, as described in Revelation. Please be aware that there are many things that happen on the earth during the tribulation that won't be discussed here simply because they are beyond the scope of this article. While these events are important, I want to focus on God's wrath on the earth during this horrible time.
Revelation starts with the letters to the seven churches.
Although the letters are written to actual first century churches, they are also directed to the seven churches throughout the Christian age. Jesus promises to save the Philadelphian church from the wrath to come, but says that the Laodiceans are poor, wretched, and blind. They are the lukewarm church. This would signify the rapture - the church being removed from the earth. Note that after this point the church is not mentioned anymore in Revelation.
