Noah and the seven souls saved with Noah in the ark represent Christ and the church that are saved out of the flood.
Noah was not taken away.The people who are eating and drinking who were oblivious to the rising waters was not Noah and his children.These people who are taken away are all destroyed off the face of the earth.
Mathew 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.
These who are taken are not raptured.They are destroyed just like the people in Noah's days who were taken away by the flood waters never to be seen again .Now let us examine the rest of the chapter.
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.
45 Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season?
46 Blessed is that servant, whom his lord when he cometh shall find so doing.
47 Verily I say unto you, That he shall make him ruler over all his goods.
48 But and if that evil servant shall say in his heart, My lord delayeth his coming;
49 And shall begin to smite his fellowservants, and to eat and drink with the drunken;
50 The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of,
51 And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth.
One thing I've noticed about people who preach the pre trib rapture is they don't watch as Jesus commands.They don't pay attention to the prophecies being fulfilled before their very eyes.
