Certainty.

J.I. Packer has written:

“Now, it is this catholic doctrine that explains the certainty and confidence of Evangelicals as to the divine truth and trustworthiness of the Bible, some, as we saw, think this robust confidence unwarrantable, and explain it as a sociological phenomenon—a piece of wishful thinking prompted by the craving for certainty which we all feel, adolescents especially, in our unsettled and rootless age. Evangelicals, it is said, cling to the idea of biblical infallibility as drowning men cling to a straw—not because it is worthy of their trust, but because they want something to cling to and there is nothing else within reach. We can now see how perverse a misunderstanding this is. The evangelical certainty of the trustworthiness and authority of Scripture is of exactly the same sort, and rests on exactly the same basis, as the Church’s certainty of the Trinity, or the incarnation, or any other catholic doctrine. God has declared it; Scripture embodies it; the Spirit exhibits it to believers; and they humbly receive it, as they are bound to do. It is not optional for Christians to sit loose to what God has said, and treat questions which he has closed as if they were still open. The truth is that the evangelical doctrine of Scripture is an article of catholic faith, and the evangelical confidence in its truth is part of the Church’s Spirit-given assurance of faith. It is strange that those who think Evangelicals odd for being sure of the biblical doctrine of Scripture do not see that so-called ‘biblical theologians’ who are not sure of it are much more odd. It is stranger still that those who accuse Evangelicals of ‘heresy’ for their view of the Bible should fail to grasp that it is not Evangelicals, but they themselves who have parted company with the historic catholic faith. One recalls the fond mother who watched the parade and concluded that all were out of step except her Johnny.”
