If John was filled with the spirit from birth (which the scripture says he was) then he would know that their was only one wrath to come - did he speak of another wrath after the "wrath to come"?
So the conclusion is the wrath of revelation is the wrath John spoke of.
Rev 16:19 And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath.
Babylon is none other than 1st century apostate Jerusalem.
Matt 21:33 Hear another parable: There was a certain householder, which planted a vineyard, and hedged it round about, and digged a winepress in it, and built a tower, and let it out to husbandmen, and went into a far country:
Mat 21:40 When the lord therefore of the vineyard cometh, what will he do unto those husbandmen?
Mat 21:41 They say unto him, He will miserably destroy those wicked men, and will let out his vineyard unto other husbandmen, which shall render him the fruits in their seasons.
