Is there a period of time between the Rapture and the start of the Tribulation? Is there a period of time between the end of the Great Tribulation and the return of Christ? Are the Two Witnesses ministering during the Tribulation doing so during the first half or the Great Tribulation? When is the Mark of the Beast implemented? Before the Tribulation, first half or Great Tribulation? How’s the Psalms 83, Isaiah 17 and Ezekiel 38-39 prophecies coming along?
The Bible doesn’t say anything one way or the other about a period of time between the rapture and the beginning of Daniel’s 70th Week. There does seem to be at least a short period of time between the end of the Great Tribulation and the 2nd Coming because Jesus said no one would know the day or hour of His return (Matt. 24:44, 25:13, etc.). The 2 witnesses come on the scene in Rev. 11:3 just before the beginning of the Great Tribulation. The mark of the beast will be introduced shortly after the beginning of the Great Tribulation (Rev. 13:16). Psalm 83 and Isaiah 17 could happen any time, perhaps this summer or fall. Ezekiel 38 will come a little later.
