In response to Bart D. Ehrman’s argument that we cannot trust in the inspiration and inerrancy of Scripture because the copies we have do not unanimously correspond so that we can perfectly reconstruct the original autographs of Scripture Daniel B. Wallace makes this statement,

We need to make a careful distinction between verbal inspiration and inerrancy. Inspiration relates to the wording of the Bible while inerrancy relates to the truth of the statement. American evangelicals generally believe that only the original text is inspired. This is not to say, however, that copies cannot be inerrant. Indeed, statement that bear no relation to Scripture can be inerrant. If I say, “I am married and have four sons, two dogs, and a cat,” that is an inerrant statement. It is not inspired, not at all related to Scripture, but it is true. Similarily, whether Paul says “we have peace” or “let us have peace” in Rom. 5:1, both statements are true (though in a different sense), though only one is inspired. Keeping this distinction in mind as we consider the textual variants of the NT should clarify matters.
