Before the parousia, concrete realities must take place: the mystery of lawlessness fully at work, the final rebellion, the abomination of desolation, and the revealing of the man of sin. All of this was announced by Daniel, reaffirmed by Yeshua, and explained by Paul, and it unfolds according to the appointed times of the Creator, not randomly.
Those who walk in the light will not be caught by surprise, because they know what must happen first.
