After carefully reading the original post I see the confusion of several answers.
I admit to being kind of lost at this point. Assuming we are in the End Times, what will be the first obvious, blatant, and incontrovertible sign that we are? Will it be a trumpet blast from the heavens, the sun turning black, the seas turning red, the Rapture? I mean something that will convince everyone instantly, religious or non-religious. Whether it's too late for some or not is a separate question, of course.
Let us look here:
( Assuming we are in the End Times, WHAT WILL BE the first obvious, blatant, and incontrovertible sign that we are?)
IS (what will be) supposed to be (what was).
If it is (what was) then Pentecost was the correct answer (empowered by the crucification of Jesus).
The (WILL IT BE) kind of sends some of us to the final day when the trumpet sounds (rapture?). If it is the last day (WILL BE) then the sign could be:
II Thessalonians 2:1
Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and
by our gathering together unto him,
2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
3 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;
4 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.
Some one else help unravel our confusion.
We are right now discussing the last age (?), and the last day (?). Both are valid discussions.
