So you have no scripture showing where he is in error?
They in no way support his eisegesis.
There is no secret pre-tribulation rapture in the Scriptures.
It is mentioned nowhere.
The burden of proof is on the claimant to demonstrate that the Scriptures clearly attest a pre-tribulation rapture.
His argument is that unless we read specific passages of Scripture against their context and against their meaning, we are "blind."
Let's take one example.
He harps on the Scriptural commonplace of "the unexpected hour."
Scripture says in several places that we will not know the hour of the parousia, that He will return at a time we will not be able to predict.
Your author abuses this clear teaching, by claiming, effectively, that what happens in that hour is that He whisks away the elect before the terrible phenomena of the Day begin.
But Scripture does not describe that hour in that way anywhere at all.
That's an external figment imposed on the text.
That is Darby's invention.
