Six of the seals from the book are now open. Remember that the only one worthy of opening these was the Lamb our Lord, no other could have done this but, a great many wanted it to be done. Having been sealed means that each of these were predetermined yet held off until the right to do so had been claimed. Even when He was proved worthy upon resurrection He then had held off until certain numbers had been fulfilled and the go ahead was given by the Father. Each unsealed judgment alone would be devastating. Together or in sequence they become a time like the earth has never known.
From our limited perspective it would be quiet logical to wonder why anyone would want to become worthy in order to open up such judgments upon mankind. Our perspective limits the nature and effects of our sin. Becoming worthy meant dying to take these natures and effects away. Our perspective limits the fact that for ions these judgments have been held off to one seven year period. Till now we have tasted enough judgment to see the need to repent but, little of the judgment that sin actually deserves. If God's mercy is not enough to turn us, if His occasional and limited judgments upon us are not enough, if His word and testimony are not enough, if His grace and provision is not enough, if the love shown in the giving of His own Son is not enough, even for having the threat of these predetermined judgments opened, what then is there that would be enough? At some point can it not be said that the remainder of mankind will not turn? Thus is the truest nature of sin exposed; it will not let go and it limits everything down to it's own justifications. Why not then this judgment? If seen from the perspective of the heavenly host looking down on this, one would have to ask why hasn't this judgment come already.
