This Rapture teaching, the best I understand it, is based off of 1 Thess 4:17 as it reads in some Bibles such as the Revised Standard. This understanding can't be correct. The idea that all good people will be removed from the planet before the earth is cleansed is the exact opposite of the last 2 verses of the second chapter of Proverbs.
Honestly, I can see it going either way. I know that many Christians are to be persecuted. Indeed many Christians are presently being persecuted and killed. In the days of the flood, there were 8 people saved. The rest of humanity was taken.
Notice what Jesus said about the flood, and his second coming. He says that those who did not enter the ark were taken. That is, they died. They were destroyed.
"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, And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be."
(Mathew 24:38-39)
Now consider what He said next:
"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."
(Mathew 24:40-41)
What do we make of this? If two people are in the field, and one of them is taken, and the other is left behind, what should we make of what actually happened to these two hypothetical individuals. It seems we can draw two or even many completely different conclusions from that which Jesus said here. First we could perceive that the person that was taken was caught up to heaven in a rapture of sorts, and that the other person was left to endure the Great Tribulation to come. Or, it could be that the person taken was killed, or even simply died of natural causes as those who were taken by the flood were, and that the one left behind was saved from God's wrath, or perhaps just happened to remain alive for now because his time had not yet come to meet his maker. We actually can't draw any conclusions based on what Jesus said here in just these few verses.
If we continue, we might see things become more clear. Jesus said:
"Blessed
is that servant, whom his lord when he cometh shall find so doing. Verily I say unto you, That he shall make him ruler over all his goods. But and if that evil servant shall say in his heart, My lord delayeth his coming; And shall begin to smite
his fellow servants, and to eat and drink with the drunken; 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, And shall cut him asunder, and appoint
him his portion with the hypocrites: there shall be weeping and gnashing of teeth." (Mathew 24:46-51)
Which guy is Jesus referring to here that will be made master of His goods, the guy that was taken, or the one left behind. How can we know? I suppose a person could be taken to heaven in a rapture and be made ruler over all of the Masters goods. Or it could be that the guy taken was killed, and the other was left behind to be made ruler over all of the Masters goods. Again, from what was said, we can make no determination as to what is being said, as to which of the servants in the field is to be made ruler over his Masters goods.
We determine what is being said as a result of our own personal subjective understandings and opinions of what is going on, and we do it regardless of the actual truth and intentions of the person we're trying to understand.
I believe the point is, if we do not desire to be included among those servants who wind up weeping and gnashing their teeth, then we had better rather focus on being wise and faithful servants to God, and stop worrying so much about revealing and determining the means and methods and time frames that God might use in completing the fulfillment of His plan for our eternal destinies.
