That's man-made Left-Behind doctrine.
It has no context in the prophetic narrative of scripture.
Good thing we got a bible
You did not investigate, Your teachers fooled you.
Mat 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.
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.
mat 25
5 While the bridegroom tarried, they all slumbered and slept.
6 And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him.
7 Then all those virgins arose, and trimmed their lamps.
8 And the foolish said unto the wise, Give us of your oil; for our lamps are gone out.
9 But the wise answered, saying, Not so; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves.
10 And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut.
11 Afterward came also the other virgins, saying, Lord, Lord, open to us.
12 But he answered and said, Verily I say unto you, I know you not.
13
Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.
