So again, you might not agree, but if you think that preterists hold to their convictions because they are simply the most plausible, then I don't think you truly understand the position.
I am not in this to agree or disagree but to fully understand the the preterist position.
You say that you believe the Bible teaches the preterist position...
You say that when you are in the pulpit you have no trouble saying 'Thus saith the Lord'...
And then show the actual interpretation of the text (for example matt 24) is that these things were going to happen in their lifetime, and they in fact happened in the destruction of Jerusalem.
But, in fact the Bible does not teach that the fulfillment happened in the destruction of Jerusalem. However, Josephus et al mentions the destruction of Jerusalem.
Therefore the preterist uses Josephus to interpret the time texts of Matt 24 and does not see this as a conflict with WCF chapter 1.
