John, the apostle, was given a revelation from Jesus about what must take place before he returns again. In Chapter 6, Jesus is given a scroll with seven seals upon it. Jesus opens six of the seals in order. The first three seals involve false Christs , war and famine being present in the world but this is not the end. This is a period of passive judgment that humans bring upon themselves. Seals four and five indicate intensification of the previous signs and widespread martyrdom. This will be closer to the end, but still not the end. Breaking seal number six ushers in the The Great Day of Wrath. This occurs during the Great Tribulation when God brings upon sinful humanity his righteous judgment.
