One thing I would like to point out........
Matthew 24:37 But as the days of Noe [were], so shall also the coming of the Son of man be.
24:38 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,
24:39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
What happened to those who were not saved by getting into the Ark ?
They were destroyed were they not ?
OK then, if Christ's 2nd coming is to like the time of Noah's flood, what makes you think that there will be any 7 years ...AFTER ....Christ returns ?
Maybe you ought to read this.....
2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and [by] our gathering together unto him,
2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
2:9 [Even him], whose coming is after the working of Satan with all power and signs and lying wonders,
2:10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
