Man's theory of a Pre-tribulational Rapture is dangerous to one's soul who believes it.
The reason is because that idea by men is designed to lead you to worship of the devil in the last days.
Lord Jesus showed that His coming to gather His Church is AFTER... the tribulation He forewarned us about (Matthew 24:29-31 and Mark 13:24-27).
The Pre-tribulational Rapture theory was never a doctrine of the early Church.
Pre-trib began to first be taught in certain churches in 1830's Great Britain by Edward Irving and John Nelson Darby. Prior to that ALL Christian Churches held to the Biblical Post-tribulational coming by Christ Jesus to gather His Church.
In Matthew 24 and Mark 13, Jesus warned about the coming of a pseudo-Christ (i.e., false Messiah) PRIOR to His return and gathering of His saints (His Church).
Christ's Book of Revelation reveals that coming false one to Jerusalem at the end will be the "dragon", the devil himself.
Men's false Pre-trib Rapture theory wrongly teaches that the Church are the first ones 'taken' in Christ's parable about the one taken, and the other left, at the end of Luke 17:34-37.
Jesus showed the first one 'taken' will be to where the fowls are gathered to eat on a dead carcase (Luke 17:37; see also the parallel in Matthew 24:28). That points to the devil's servants, and where the devil will be.
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.
THE CATCHING AWAY OF THE SAINTS
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.
THE THIEF
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....
DRUNKEN SERVANT
...49 And shall begin to smite his fellowservants, and to eat and drink with the drunken;..
NOW CHECK THIS OUT
15 For this
we say unto you
by the word of the Lord(QUOTING JESUS' WORDS), that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
THE CATCHING AWAY OF THE SAINTS
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
18 Wherefore comfort one another with these words.
5 But of the times and the seasons, brethren, ye have no need that I write unto you.
THE THIEF
2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
4 But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6 Therefore let us not sleep, as do others; but let us watch and be sober.
THE DRUNKEN SERVANT
7 For they that sleep sleep in the night; and they that be drunken are drunken in the night.
