Those believers on earth at that time will be very aware when the day of the Lord is coming. For one thing they will see the signs of the sun, moon and stars............immediately after the tribulation. So your comments are left wanting..........again
That's the point, many Christians are in darkness to the fact that Christ does not return until the 7th trump. That's also why many are setting themselves up to take part in the falling away that Paul taught about.
Christ taught that Christians will come up to him when he returns and he will turn them away and saying he doesn't know them.
But the only way that the day doesn't over take us as a thief is if we that wait upon the true Christ and don't fall off for the first one that arrives.
I Thessalonians 5:5 "Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness."
I Thessalonians 5:6 "Therefore let us not sleep, as do others; but let us watch and be sober."
We are to watch as Christ and Paul taught. What do we watch for? The signs that Christ lays out in the gospels, Paul and John being witnesses as well. And to know the order of events as Christ lays out in the seals. The very first one of importance -Antichrist arriving on the first white horse. These are the things we must watch for so that day does not overtake us.
That's the point. These are the ones that will be looking up and know their redemption is near.
The rest as I said, will think Christ is already here (most of the world)
Daniel 11:32 "And such as do wickedly against the covenant shall he corrupt by flatteries; but the people that do know their God shall be strong, and do exploits."
These are the Christians that know from the very first seal that Antichrist will be here before the true Christ. They know the true Christ doesn't return until the 7th trump. The rest of the world will be thinking peace and safety and then then God's wrath will be upon them.
When Christ says he comes at an hour most do not expect it's because, as I said, many of the Christian world expect him to arrive first. That's also why he warns to not us be harvested out of season. Some will be harvested when the anti (instead of) christ comes and that's why many families will betray one another and so on at that time.
That's why Christ taught that "one will be taken, the other left.
Matthew 24:40 "Then shall two be in the field; the one shall be taken and the other left."
Do you know what the word "taken" means in this verse? It is the Greek word 3880 paralambano and it means to receive near i.e. associate oneself with (in a familiar intimate act or relation, to learn, to receive.
These are the ones that will be taken in by Antichrist, that is the snare that comes over the entire world. And they will be the ones receiving his mark.
Paul talks about a falling away which must be substantial. These Christians will be thinking he is their true savior.
If taken meant anything else such as a rapture, Greek word 522 would have been used as it is in this verse,
Matthew 9:15 "And Jesus said unto them, "Can the children of the bride chamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast."
The word taken in this verse is apairo and it actually does mean lift off, remove, take away.
Christ is talking about two different types of people, those taken by antichrist and those left. And if you go by the rest of the NT these would be those that are left "standing". These are the ones that will be able to stand before the son of God. The rest will be praying for mountains to fall on them.
This is why Paul says that day doesn't have to overtake us as a thief.
This is also why he's teaching us to have the full armour on to be able to stand in that "evil day"
You still never had a thought on what that "evil day" might be?
