They can be just as false, like the one you quoted and I immediately found error in. Alexander was it? If I found error that quickly in a small portion of his book that you quoted, then how much more would I find if I read his whole book?
As vekky's reply suggests, you have a strange concept of what constitutes error. By your definition, yes, you will indeed find 'error' in every single paragraph of his writings. Like me, he belongs to the 'Jacked Up' school of prophetic interpretation - just like every inspired writer of the NT in fact.
His interpretation of the symbolic significance of Hosea's wife is a widely held view within the ranks of conservative scholarship, and is even advocated by no less an authority than the mighty Hengstenberg himself. In fact, those who hold this view are only slightly outnumbered by those who believe she was an historical person, even though she is still regarded by them as a type for faithless Israel. To call this 'error' is a severe case of over-egging the pudding, and greatly devalues any impact your criticism of him might have had.
But by all means continue to deprive yourself of the rich pickings that are available to you in his writings, lest you unwittingly fall victim to yet more such grievous 'errors'.
