The principal reason given by those who believe in the plenary inspiration of the Bible, for holding to this doctrine, is the necessity of _some_ authority. The argument is this: Unless every part of the Bible is believed to be fully inspired, some part of it may be believed to be erroneous; and if we admit error in any part, the Bible loses its authority, and we do not know what to believe. The doctrine of literal and plenary inspiration rests, therefore, in the last analysis, on no basis of fact, but on a purely _a priori_ argument. Let us therefore examine this argument, and see what is its force. Revelation, it is said, is a communication of truth with authority. It is truth shown to us by God, not truth reasoned out by man. Its value is, that we can rely upon it entirely, live by it, die by it, without doubt or hesitation. We do not want speculation, opinion, probability; we want certainty; otherwise religion ceases to be a power, and becomes a mere intellectual amusement. The only religion, it is added, which is of any real value, is that which carries with it this authority. The outward world, with its influences and its temptations, is so strong, that we shall be swept away by it unless we can oppose to it some inward conviction as solid and real. Amid the temptations of the senses, the allurements of pleasure, the deceitfulness of riches, will it enable a man to hold fast to honesty, temperance, purity, generosity—to believe that in all probability these things are right, and that there is something to be said in favor of the opinion that God approves of them? Will it help him, to think that unless the writer of the Gospel is mistaken, or his words mistranslated, Christ may have said that goodness leads to heaven, and sin to hell? No. We need authority in order to have certainty; and we need certainty in our convictions in order that they should influence us deeply and permanently. This is the chief argument in favor of the plenary inspiration(11) of the Bible. We see it amounts to this—that it is very desirable, for practical purposes, that we should believe everything in the Bible to be true.(12) In reply to this, we ought first to say, that the question in all these cases is not, What is desirable? but, What is true? We should begin by investigating the facts. We should ask, Does the Bible anywhere say of itself that it is inspired in this sense? Do any of the writers of the Bible declare themselves to be thus inspired, so that all that they say is absolutely true in every particular? Does Christ say that those who are to write the Gospels or the Epistles of the New Testament shall be thus guarded against every possible error? Or is there any evidence in the books themselves that the writers were thus protected? Do they never contradict each other or themselves? Do they never contradict facts of nature or facts of history?
