GOD's Seal is for His servants[Rev.7:3] - and it is on the inside of the brain; near the intersection of the eyes and ears. The Seal = the Truth. This makes the Seal untouchable by the Vials, or the #1 tool of the Enemy = deception.
Zechariah 1:18 mentions the Four-Horns: which are in order - Education, Economics, Political, and Religion. These are the bad-figs that were produce from the Tree of Knowledge of good and evil. This is their season and they are coming out of the closet; world-wide. They know Whom their Father is, and will Not worship another.
There are many "keys" in Zechariah 1:18,19, for individual study, and deliverance. Vs. 20 mentions Four-Carpenters - which are on assignment. For those who know the Truth, move out of their way. Pseudo-teachers and Pseudo-leaders can lie and deceive the people; but these Four-Carpenters know who makes up the House of Israel - and who the Gentiles are: and so should we.
Matt.24:5 "Many will come in My name". Christ = the Anointed, Savior, the Answer, etc.. These are also Pseudo-prophets, politicians, and religious ones.
Matt.24:7"Nation against nation, and kingdom, against kingdom". Luke 21:9 "Be not terrified".
The Seal of Truth makes one untouchable. Sadly, many of the leaders are Fakes[hypocrites]; including 90% of those preaching, writing, and in front of cameras. During this time, we are to "stand", but not in the way!
