What happens during the last three and a half years of the tribulation?
At the midpoint, the Antichrist comes in, defiles the Temple, and turns on the Jew. The final three and a half years are a horrible period when the earth comes under the wrath of God and Satan, the power of the holy people is scattered, and all these things are finished.
Les explains that although the tribulation is seven years, Daniel is foretelling the last three and a half years, described as a time, times, and half a time. The midpoint is when the Antichrist will come in, defile the Temple, and turn on the Jew. That horrible period is when the earth comes under the wrath not only of God but also of Satan himself. Daniel says that when he shall have accomplished to scatter the power of the holy people, all these things shall be finished. Daniel heard but understood not, and he asked what shall be the end of these things. The Old Testament prophets got a glimpse of coming things, but not the full picture, and Daniel got enough of a glimpse that it scared him down to his shoelaces.
And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.
