Hebrews 10:23-25 - "Let us hold fast the profession of our faith without wavering; for He is faithful that promised; And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as you see the day approaching."
What do you think the writer of the Book of Hebrews meant by "as you see the day approaching." Could it be "the day of the Lord," a phrase which appears twenty-seven times in twenty-six verses in the King James Bible? If so, does it refer to a literal day, or a period of about 1000 years (2 Pet. 3:8), which would include the Rapture of the Church, Israel's seven-year Tribulation, and the seventh dispensation, Christ's Millennial Kingdom? Notice that the "day of the Lord" includes the Rapture (1 Cor. 5:5; 2 Cor. 1:14), the Tribulation (Isa. 13:9; Zeph. 1:18), and the Church has to be gone because "...God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ" (1 Th. 5:9; Rev. 3:10).
First of all, the Book of Hebrews was written to Christians who had formerly been Jews, which can be seen in verses 1:1-2: they refer to the Old Testament prophets speaking to "the fathers," and of the readers having been spoken to by the Son of God. Secondly, 1 Th. 5:2 and 2 Pet. 3:10 describe His return as being like a thief who comes in the night: at a time when He is not expected. The Rapture is the only event of the three that is "unknown." The agreement between Antichrist and Israel begins the seven-year Tribulation, and the Abomination of Desolations marks the mid-point of the seven years (Dan. 9:27); and the Second Coming of Christ occurs exactly seven years after the agreement begins (Mt. 24:29).
While no man "knows the day nor the hour" (Mt. 25:13), there are apparently clear signs that the time is rapidly approaching (Mt. 24:3-44; 1 Th. 5:1-4; 2 Tim. 3:1-5; etc.)! Christians will not be caught off-guard because we recognize the events leading up to the beginning of the day of the Lord. However, the rest of the world can know the time-table once we are gone; the Tribulation and the Second Coming of Christ to establish His Millennial Kingdom will occur at exact times.
BECAUSE OF WHAT HAPPENS AFTER THE CHURCH IS RAPTURED TO HEAVEN,
ACCEPTING CHRIST AS YOUR LORD AND SAVIOR NEEDS TO HAPPEN TODAY!
