Truly, if the last DAYS were 2,000 YEARS ago, then something surely is amiss.
The last section of any period is at the end of that time period.
the last days of school
the last days of a pregnancy
the last days of summer vacation
the last days of a prison sentence
the last days of World War II
Each of the time periods has a specified length. The last days are in relation to that time period. It is a VERY SMALL PORTION of the related time period and could vary significantly depending upon the original length of the time period.
the last days cannot be considered to be the same length as the original time period.
the last days cannot be considered to be half of the original time period, a third, nor a quarter - it is the END period of the original time period.
I suppose many here are forced to believe Joel's prophecy from Acts 2 is that the last days of the church correspond directly with its infancy, or its very beginning. That is adamantly false because that makes the last days equal to the length of the original time period.
All this stuff is true if you consider the last days as being associated with the old covenant temple system. These last days were approximately 40 years in length compared to the over 1600 years that it had existed prior to Christ's ministry. The old covenant system was put out of its existence at the destruction of Jerusalem a long, long time ago, folks!
