What does Daniel 12:1 mean?
The angel Daniel saw in a vision at the Tigris River (Daniel 10:1) continues to speak. He has delivered a series of prophecies, recorded in Daniel chapter 11. Those predicted many of the major historical events happening around Judea in the fourth through second centuries BC. Near the end, the angel's predictions shifted, to look much further in the future. Here, the angel speaks in extremely broad terms. This begins a short passage which touches on some of the most important themes in Christian theology.Michael is one of only two angels named in Scripture. The other is Gabriel (Daniel 8:15–16; 9:21–22; Luke 1:26), who is probably the one giving this information to Daniel (Daniel 10:18–21; 11:2). Michael is described as "the archangel" (Jude 1:9). His role seems to involve leadership over the armies of heaven (Revelation 12:7). Earlier, Michael was said to be involved in a supernatural battle with a "prince of the kingdom of Persia" (Daniel 10:13), likely a fallen angel of some kind. That demon was apparently primarily concerned with that region of the world; Michael seems to be the angel most directly concerned with Israel.
What the angel describes here corresponds with a time often called "the great tribulation." This is often associated with the second half of a seven-year "tribulation" during the end times. Jesus also commented on this era (Matthew 24:9–26). Most interpreters believe this series of events will involve the beasts of Revelation (Revelation 13:1–4, 11–17) and some type of treaty with Israel (Daniel 9:27). According to this view, the midpoint of this seven-year period will include "the abomination of desolation" (Matthew 24:15), triggering this time of unprecedented suffering.
Some interpreters believe the start of this "great tribulation" corresponds to the war mentioned in Revelation, where Michael and the other angels drive Satan and his demons onto earth. Satan then vengefully attacks the Jewish people (Revelation 12:7–12). This will be the worst persecution of Israel's entire existence. After a series of supernatural events and disasters, Christ will return to earth (Revelation 19:11–15), to rule a kingdom including those Israelites who survived (Zechariah 13:8–9).
This verse also notes a "book." This does not seem to be a literal paper-and-ink object, but a reference to God's record of those who have been saved. This idea is used often when speaking of salvation and God's knowledge of who is a true believer (Exodus 32:32–33; Ezekiel 13:9; Luke 10:20; Hebrews 12:23; Revelation 20:12).
