Everything in the contest which Apologetics has to meet centers here: Is sin a reality, an abnormal condition, or a stage of education, a process of development, a lesser good? Wherever sin is, there will be opposition to holiness. It is natural for sin to oppose holiness, and to deny a holy God. ¶ The felt reality of sin is necessary to the possibility of redemption. Christianity is essentially a redemptive system. Incarnate love was crucified. A man with no sense of sin must oppose Christianity, in its doctrine of grace as well as of sin. ¶ In this statement it is by no means asserted or implied that all objections to the Bible and Christianity are only the signs and manifestations of man’s inborn and inbred corruption; that historical, philological, and doctrinal criticism come invariably from a sinful unbelief — stiil less, that when reason thinks and speaks, its utterances are to be set down to the account of a godless rationalism. Far from it. There are undeniable difficulties in respect to history and science which must be investigated. There are signs and wonders which would stagger any one, unless the need of them and their historic reality can be clearly evinced. Conscience and reason have their rights. Science has its lawful sphere. We are to prove (test, try) all things — even the Scriptures, even the doctrines of our faith — and hold fast that which is good. ¶ If the Christian system cannot establish its claims and authority in the view of reason and conscience (their rights being carefully weighed and defined), it will be in vain for Church or Pope to call upon the nations to believe in their own infallible authority, as settling all questions of right and wrong, truth and falsehood, for time and for eternity. No; we are in the conflict, and it is only by going through it that we can get the victory.
