The King James Bible is loaded with answers - but must be read. It is broken down into Covenant One; and Covenant Two. The often over-looked part is Testimony, which is present, from beginning to end. This less than exciting information, is worthy of chewing on [meditating], until the obvious becomes clear.
Testimony = a witness. To be a witness, I. E. testify, before a judge; bear record.
Ex.16:34 "As the LORD commanded Moses, so Aaron laid it up before the Testimony, to be kept." GOD-Elohim: plural, is the Ultimate Witness. And we are in HIS image.
Immanuel-Christ-Jesus [Matt.8:1-4] healed a man of leprosy and gave the instructions that Moses commanded, for a Testimony unto them. The meat: It is a honor to be a Witness [Matt.10:18] for the LORD and against those that are in need of Salvation.
Luke 21:13[Mark13, and Matt.24] the ultimate Testimony will be before "a beast" - then, - "The Beast". The Holy-Spirit speaks through us: we have nothing to fear, and are not to "premeditate on what to speak". Short of this big event, we are to be Witnesses; just as John the Baptist, and the Apostles, etc..
The Witness has to "see, or hear" [Jn.3:32] things of Immanuel-Christ-Jesus; which is the Word, from start to finish. A Testimony result from going through, Vs. running and hiding. Rev.12:11 is a key - practice often. The 144,000 are Sealed, and know the Truth: these are GOD's church[singular]. They are the counter-balance for the "labor-pain-trouble of the world of chaos.
