Hi Vanderhoven,
What I can say is that late 19 century, beginning of 20th century it was a massive transformation in the whole world. Cultural, educational industrial revolutions. It was something that the humanity haven't experienced before. The gospel was preached in the whole world by different protestant denominations. We witnessed 2 world wars, a great depression, Spanish flu who affected mainly young healthy people and literally stopped the first world war. Whether all these coincidences with Jesus second coming and satan's end in heaven is up to everyone to decide.
I believe Jesus have chosen a faithful slave for a special purpose to announce his kingdom. I don't think there is an identifiable faithful slave today as the preaching was done and now we are at this point:And many false prophets shall rise, and shall deceive many. And because iniquity shall abound, the love of many shall wax cold. But he that shall endure unto the end, the same shall be saved. There is parable in the bible where it said that the door will be shut. And also Jesus said But pray ye that your flight be not in the winter, neither on the sabbath day: for then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. Matt 24:22-24
I believe that lately God permitted that evil slave to conduct a deceptive work when the true preaching was complete.
"Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God (replacing Jesus). Remember ye not, that, when I was yet with you, I told you these things? And now ye know what withholdeth that he might be revealed in his time. Even him, whose coming is after the working of Satan with all power and signs and lying wonders, and with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: that they all might be damned who believed not the truth, but had pleasure in unrighteousness."
2 Thessalonians 2:3-6, 9-12
If we go by what the bible says the temple of God is where his church is: " Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are." So the "man of sin" can only enter where Christ church is at the time of the end.
1 Corinthians 3:16-17
I believe the sabbath day coincidences with a period before the great tribulation when preaching activity will be stopped or hijacked by the man of sin. And the winter coincidences with the the start of the great tribulation. Throughout this period is still possible to flea but will be hard to find the right path. However, sincere people who want to practice pure worship by keeping themselves unspotted from the world and who do not receive the sign of the beast will be given an opportunity. God is faithful to his word and he will give every human being the opportunity to find him.
