The main argument in support of a mid-tribulation rapture is in equating the last trumpet of 1 Cor. 15:52, with the trumpet of Revelation 11:15. The suggestion is that the last trumpet of 1 Cor. 15:52, which signifies the Rapture, is the same as the 7th trumpet of Revelation 11:15, which occurs at the mid-point of the Tribulation Period. This implies that the rapture will take place at that time.The last trumpet of 1 Corinthians 15:52 is the last trumpet of the age of grace, the church age, and the 7th trumpet of Revelation 11:15 is the last trumpet in a series of judgments and is not related to the rapture.
Mid-Tribulationism takes away IMMINENCY which is clearly taught in scripture. "Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh" (Matthew 24:44).
"But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only" (Matthew 24:36). If we say the rapture takes place at the Midtribulation point then everyone would know both day and the hour.
A Unique Generation - The NewTestament scriptures teach us that there will come a generation of believers who will see the signs of the approaching Day of the Lord (Tribulation Period) and know that the rapture is near, because, it will precede the Day of the Lord.Paul taught this in 1 Thessalonians 5:4, He taught that there would come a generation who would recognize the signs of the approaching Day of the Lord. He said, "But ye brethren are not in darkness, that That day should overtake you as a thief."
The writer to the Hebrews taught the same thing in Hebrews10:25. He said, "Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching." When you see the Day of the Lord approaching this is what you ought to do, be faithful in assembling together, and exhort one another. That clearly implies the rapture is near for a specific generation.
Today we see the shadows of events that will take place in the tribulation period. We see the preparations now under way for the coming world government, the Day of the Lord is at hand. We see the foreshadowing of the coming world church, the Day of the Lord is at hand. We see the preparations for the all three wars of the tribulation period, the Day of the Lord is at hand. We see the alliance of Russia and Iran forming for the war of Ezekiel 38-39, the Day of the Lord is near. We see the technology in place for the mark of the beast, the day of the Lord is near. We see the revived Roman Empire forming in Europe, the day of thr Lord is at hand.
Fulfilled Prophecy today confirms that we are that generation! The signs of the soon coming Tribulation Period are multiplying all around us. Dr. John Walvoord has stated what an ever-growing number of pastors and Bible teachers believe. He stated, "Never before in history have all the factors been present for the fulfillment of prophecy relating to the End Time Event. Only in our generation have the combined revival of Israel, the formation of a World Church, the increasing power of Islam, the rise of Occult, the Worldwide spread of Atheistic Philosophy, all been present as a dramatic setting for the fulfillment of Prophecy. These all indicate that the Day of the Lord is near at hand.
