Then shall two be in the field; the one shall be taken, and the other left. Two women shall be grinding at the mill; the one shall be taken, and the other left. Watch therefore: for ye know not what hour your Lord doth come. 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. Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh.
(Mat 24:40-44)
And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares. For as a snare shall it come on all them that dwell on the face of the whole earth. Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things (ALL, means ALL He mentioned above) that shall come to pass, and to stand before the Son of man.
(Luk 21:34-36)
Rev_3:3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
Rev_3:10 Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
The churches are made up of different bodies and Jesus addressed the 7 located in Asia Minor (Turkey) He mentioned "ONE" being taken, one left so it's just not the Church but each person is examined if they are doing what they are suppose to be doing when He does come. (Matt 24, Luke 21)
The promise with 3 Scripture wittiness (I gave 3 places where it says this) leaving out what Paul said that we do Escape God's wrath to come, all indication is that those doing what God had called them to do faithfully will escape what is about to come on the whole earth.
As for being saved, Jesus or any other mention was given that a person not faithful as a believe would not get to be saved or have to go to hell. It just says they will have to face what is to come on the whole world.
I am taking a Pre-Trib position.
A Post trib position means of course we hang out while God trashes the planet, but the position of our standing with the Lord should not change as we should all obey and serve him.
I don't consider a Preterist view valid enough to mention. They put clear events as Hyperbole and make believe which is not acceptable. The stars will vanish and that is yet to happen.
