Revelation chapter 16; the vial (bowl) judgments.  The vial judgments differ from the seal and trumpet judgments in that they are far more severe, both in their global extent and intensity.  Divine mercy is no longer mixed with judgment and wrath.  They are given to warn men of even greater wrath to come - they ARE the greater (earthly) wrath!  Nor are they are given to convict men of their sins, but are the pure expression of God's righteous wrath and vengeance.  The only glimpse of mercy in that they are relatively short in duration.  They are horrendous, but will only last a few years, after which the sky will remain sunny and clear for 1,000 years!
