And so while signs may have occurred at the time of formation of the Zionist state of Israel, the signs had nothing to do with God blessing that which His prophets say is not to happen until Christ returns (example: Eze 21:25-27). God's signs have meaning for all of God's people all over the world, not just those of the tribe of Judah. These particular signs are warnings to clean up out houses. Had the past signs been significant in relation of the events that took place, the signs would have all occurred well before the events began to happen. All throughout His Word, nothing happened without it first being announced well ahead of time, by signs in the sky or by Word of God through His prophets.
Maybe they weren’t warnings. Maybe they were “imprimaturs”.
Websters says for imprimatur ...
... a mark of approval or distinction.
... sort of like those political commercials where the candidate says, “I approve this!” (or “I sanctioned this.”).
