Going back through the posts, I don't see where b-d stated that it began at the times of Adam. I believe that b-d was refering to the "last days" as the time from Pentecost to now.
However, 2 Timothy and 2 Peter do not share that view but rather continue to speak of the last days as a future event: "But realize this, that in the last days difficult times will come." [2 Tim 3:1]
Of course they speak of future events. They are future things in these last days
“Blue-duncan says the last days started with Adam.”
What I said was “the “end of times” began as soon as Adam sinned and the only thing keeping us from the “day of the Lord” is His grace and mercy.”
