Pretty simply , The Lord Returns for His Church on The Last Day and The Last Trumpet. If one is taken and another left I assume you are using Matthew 24 as a proof text for 2 comings of Christ. More specifically according pretribulationalism for the church and later with the church. Problem is Absolutely it is pretty clear that Matthew 24 is the same event as the first resurrection described at the coming of the Lord and the catching up of the saints as described in 1 Thessalonians 4:16.17. God has not appointed us to wrath but to obtain salvation by our Lord Jesus Christ , I myself was not dogmatic about my endtime beliefs until I was taught from scripture. In the seventies during the outpouring. of the Spirit worldwide during the Jesus people days pretribulationist books appeared in mass. Usually dramitized , Calvary Chapel took up this view . The Blood of Cross is essential , be ready for the Lords return is essential , end time views as to the nature of the Lords return is not essential . I pursued God and when it was my time to firm up what I believed about The Lords return , I found the overwhelming literally overwhelming message of scripture was post tribulationist view that catching up of the saints was at The Second Coming of Christ. The seven year gap , between the rapture and the Lords return turned out to be simply theological speculation. Scripture is not dispensationalism is the key to getting the timing down. Pretribulationists assert that there will be a seven year Great Tribulation where bowls of wrath are poured up the earth and the scripture says that we are not appointed to wrath. I assume I won’t be . I am not looking for a rapture prior to the Second Coming of Christ. Other wise the Blessed Hope would be the rapture , instead of the return of Jesus the second coming of Christ , not the third. I don’t know how it all works because frankly I am convinced that the church is in the world when living believers are caught up to meet the Lord in the air, but not preceding those who sleep the dead in Christ rise first. Got plenty of scriptures to support this view . Matthew 24 is not a proof text of 2 comings of Jesus or shouldn’t be anyway.
You skipped it.
Omitted it.
Here are the same verses you skipped;
Now let's look at the other coming of Matthew 24
37 But as the days of Noah were, so shall also the coming of the Son of man be.
38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,
39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
40 Then shall two be in the field; the one shall be taken, and the other left.
41 Two women shall be grinding at the mill; the one shall be taken, and the other left.
42 Watch therefore: for ye know not what hour your Lord doth come.
We see vividly pictired;
The prejudgemnt setting
Noah entering the ark( the vessel taking him miles into the sky) where he would dwell in the heavens FOR THE DURATION OF The JUDGEMEMT/TRIB/WRATH.
Then wecsee the catching away PREJUDGEMENT, of one believer raptured, one staying. Vividly pictured.
Then we see the pretrib command;
42 Watch therefore: for ye know not what hour your Lord doth come.
43 But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.
44 Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh.
Very plain and vivid depictions of 2 SEPARATE AND TOTALLY DIFFERENT "comings".
