What does Mark 13:19 mean?
The tribulation is a seven-year period during which the Antichrist will rise in power and persecute Christ-followers and God will judge the world. The first three and a half years will be horrible. But, as Daniel corroborates (Daniel 12:1), the last half will see the worst destruction in the history of the earth, even including Noah's flood.During the siege and destruction of Jerusalem in AD 70, Josephus records that 1.1 million civilians died of starvation or violence. Another 97,000 were sold into slavery, many forced to become gladiators. During the Holocaust of World War II, 6 million Jews were killed, about 35% of the estimated Jewish population.
These disasters will pale in comparison to the end times. Zechariah 13:8–9 warns that during the tribulation, two-thirds of all Jews will be killed. Revelation 6—16 outlines the additional horrors the world will experience. These include an earthquake that will flatten every mountain and sink every island (Revelation 16:17–21). All sea life will be destroyed (Revelation 8:9; 16:3). Billions will die.
The last half of the tribulation is also known as the great tribulation, or "wrath of God." This impending judgment on sin refers to both the end-time tribulations and the eternal, all-consuming consequences of defying the Creator (Romans 2:5; 5:9; Ephesians 5:6; Colossians 3:6). This is God's response to the calls for justice people have prayed over the centuries. The evil world, as a whole, will face the repercussions of their rebellion against God. Until then, whoever rejects Jesus carries God's impending wrath on them (John 3:36).
It is easy to forget, especially as Christian believers, that we all deserve the same fate. There is nothing inherent in any of us that makes us undeserving of earthquakes, famine, fire, and death. All of humanity deserves to experience God's wrath, whether in the end-times tribulation or in an eternity in hell.
The good news is that Jesus makes this fate optional. Those who submissively and faithfully accept His sacrifice for our sins, making our relationship with God right, will escape God's wrath (Romans 5:9). It doesn't mean we won't see hardships, such as war and natural disasters. But we will be free from God's righteous judgment of our sin.
