Not exactly agreed. Although we don’t know the hour, we’re supposed to watch so we won’t be caught unaware (same passage). That in itself tells us that we WILL know the season. (Besides, if not, why would Messiah tell us what to be watching for so extensively in that very chapter?) Paul reiterates this by saying that it’s those in darkness for whom the Day of the Lord comes like a thief, not for those who are sons of light (1 Thess 5).
10 But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.Christ will return suddenly without warning and this life as we know it will all be over. We look for new heavens and a new earth in which righteousness dwells.
11 Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness,
12 looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat?
13 Nevertheless we, according to His promise, look for new heavens and a new earth in which righteousness dwells.
14 Therefore, beloved, looking forward to these things, be diligent to be found by Him in peace, without spot and blameless; (2 Peter 3)
Anyone who says they are looking for a future millennial kingdom does not know the Scriptures.
