And your point is...?
The rest of the Bible (that you always ignore when focusing on a verse that seems to say what you like to believe.) describes the Paraousia like the days of Noah. People ignored Noah a preacher of righteousnes and his ark building. The parousia like the days of Noah includes more than the flood and more than the tribulation and the rock that hits people on the head. The axiomatic point is that the Parousia is similar to the days if Noah.
You fail to see that during the days of Noah SEEmed to be ordinary to people who took no note—but Noah knew that his days were not ordinary. The days of the Parousia are similar. So contradicting your beliefs, the Scriptures show that the Parousia includes a period of time when there was an Elephant in the room and nobody noticed until the gt hits them over the head and the tribes beat themselves in lamentation when they see miraculous proof.
