Prophecy is like a road sign warning of dangers ahead and urging those who take notice of the warning to seize corrective action before the danger the road sign warns of becomes impossible to avoid. If corrective action is not taken, disaster will surely ensue.
Many in the Christian world, however, studiously avoid taking note of the Prophetic Scriptures; either that or Christians are encouraged to not bother with the Prophetic Scriptures because they are simply too hard to decipher. Instead they are encouraged to believe the many false prophets who have arisen today who claim they have a special conduit to God that others do not possess.
Antipas, however, relies only on the Prophetic Scriptures and puts no reliance on such so-called latter-day prophets. The conclusions reached by Antipas are solely based on the WRITTEN Word of God - that is to say, the Bible; its trust is in those words in the Revelation that say:
"BLESSED IS HE that readeth and they that hear the words of this prophecy (meaning the prophecies contained in the written word of God) ..." (Rev. 1:3a)
No other book in the Bible possesses such an astounding introduction. The verse continues - giving credence to our admonishment above warning Christians to take corrective action based on the Prophecy of the Word of God:
"[BLESSED is he] who keep those things which are written in them, for the time is at hand." (Rev. 1:3b)
