Some people believe the Day of the Lord will begin at the 6th seal where it is written, "the great day of His wrath is come." Others think this is just an announcement and the real Day will begin with the 7th seal.
I believe the Day MUST start in one of these two places. Please give which of these two points (6th seal or 7th seal) you believe is the true START of the Day of the Lord, and your argument as to why.
(Note, this will not include any arguments that the Day of the Lord will be the last event of the 70th week, or the theory that the Day will come with His coming to Armageddon. I already know these two theories are bogus.)
