Greetings Roadkill,
First of all, you are correct in that the Second Coming and gathering of the church as being two separate events. But regarding what you said "Jesus' second coming will come in the twinkling of an eye. The Rapture is not so," this is false. In this case you have the two events backwards, for there is a multitude of signs leading up to Christ's second coming, namely the antichrist establishing that seven year covenant which initiates the seven years, the setting up of the abomination which marks the middle of the seven years, the seals, trumpets and bowl judgments, which are the wrath of God and which will be taking place during that seven year period, with Christ returning shortly after the 7th bowl has been poured out. So No! The second coming of Christ will not be like a thief in the night. It is the gathering of the church that will be like a thief in the night, for that event has no signs and can take place at any moment.
Also, you have the gathering of the church taking place over a 3 day period, when there is absolutely zero scripture to support this. In fact, the resurrection of the dead and the changing of the living will take place in close proximity to each other. The only reason that the living are changed, is because they will still be alive when the Lord comes to gather the church. For example, scripture states that when the dead resurrect they will be caught up in the air, then immediately after that we who are still alive and remain will be changed and caught up with them. According to you, those who will have been resurrected will be gathered and waiting in the air for three days for the living believers. The whole event of the dead rising and the living being changed and caught up will take place in a Nano second. The people of the earth will realize something has happened because of the great number of people missing.
Where in the world did you get the above information from? It surely doesn't come from the word of God.
Where is it stated in scripture that it is only those who are 25 years and younger who will be transfigured? Don't bother, because there is no such scripture! What about those who are 26 and older who are in Christ and are still alive at that time and who will have also been looking the blessed hope? I submit to you that every person in Christ who is alive at the time of the resurrection, regardless of age, will be changed and caught up.
Scripture would disagree with you regarding your claim that no children will be conceived during the tribulation period and that because the following scripture is regarding Israel's fleeing into the desert as a result of the abomination being set up, which initiates the great tribulation and demonstrating that there will be women who are pregnant and those who are nursing children.
"How miserable those days will be for pregnant and nursing mothers! Pray that your flight will not occur in the winter or on the Sabbath. For at that time there will be great tribulation, unmatched from the beginning of the world until now, and never to be seen again. If those days had not been cut short, nobody would be saved. But for the sake of the elect, those days will be shortened
There is no way to know when Jesus will return to the earth to gather His church. You are correct in that the events of Rev.12 with the Satan and his angels being cast out of heaven and the woman fleeing out into that place prepared for her by God. But the only way to know when the middle of the seven years is, is to know when that seven years begins. And the only way to know that, is when that antichrist is revealed and establishes that seven year agreement with Israel. Otherwise, there is no way to know when the middle of the seven years will take place, until the seven years is initiated.
Most everything that you have claimed above is pure conjecture, because there is no scripture for it and neither did you provide any to back up your claim.
