Which verses did Les say culminate the first three and a half years of the tribulation?
The first three and a half years of the tribulation are culminated by the events described in verses 5 through 13, or really verses 5 through 12, since verses 13 and 14 carry on all the way to the end.
Les explains that verse 15 marks the midpoint of the tribulation. He says the first three and a half years have been culminated by the events in verses 5 through 13, or 12 really, because verses 13 and 14 go all the way on to the end. He then notes that in verse 15 Jesus says, 'just as soon as you see those three words, Daniel the prophet,' which validates Daniel's prophecy.
