1. "Will a believer be saved, no matter into what course of sin he may fall, and die in?" A true believer will, infallibly, be saved; but we consider that salvation includes, not only full deliverance from the future consequences of sin, but from the present power and practice thereof. And, hence, if we find a person living in sin, and yet talking about his assurance of salvation, we look upon him as an antinomian, and not a saved person at all. "If we say that we have fellowship with Him, and walk in darkness, we lie, and do not the truth." The believer may fall, but He will be lifted up; he may be overtaken, but he will be restored; he may wander, but he will be brought back, because Christ is able to save to the uttermost, and not one of His little ones shall perish.
2. "Will the Holy Spirit dwell in a heart where evil and unholy thoughts are indulged?" The body of the believer is the temple of the Holy Ghost. (1 Cor. vi. 19.) And this precious truth is the ground of exhortation to purity and holiness of heart and life. We are exhorted not to grieve the Holy Spirit. To "indulge" evil and unholy thoughts is not christian walk at all. The Christian may be assaulted, grieved, and harassed by evil thoughts, and in such a case he has only to look to Christ for victory. Proper christian walk is thus expressed in John's first epistle: "We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not." (Chap. v. 18.) This is the divine side of the question. Alas! we know there is the human side likewise; but we judge the human side by the divine. We do not lower the divine to meet the human, but ever aim at the divine notwithstanding the human. We should never be satisfied with anything lower than 1 John v. 18. It is by keeping up the true standard that we may expect to raise our moral tone. To talk of having the Spirit and yet "indulge" in evil and unholy thoughts is, in our judgment, the ancient Nicolaitanism (Rev. ii. 6, 15), or modern antinomianism.
3. "If it be so, then, will not people say, they may live as they like?" Well, how does a true Christian like to live? As like Christ as possible. If one had put this question to Paul, what would have been his answer? 2 Cor. v. 14, 15, and Phil. iii. 7-14, furnish the reply. It is to be feared that the persons who ask such questions know but little of Christ. We can quite understand a person getting entangled in the meshes of a one-sided theological system and being perplexed by the conflicting dogmas of systematic divinity; but we believe that the man who draws a plea from the freedom, sovereignty, and eternal stability of the grace of God to continue in sin, knows nothing of Christianity at all, has neither part nor lot in the matter, but is in a truly awful and dangerous condition.
As to the case which you adduce, of a young man who heard a minister state in his sermon that "once a child, always a child," and who took occasion from that to plunge into and continue in open sin, it is only one of thousands. We believe the minister was right in what he said, but the young man was wrong in what he did. To judge the words of the former by the acts of the latter is utterly false. What should I think of my son, if he were to say, Once a son, always a son, and therefore I may proceed to smash my father's windows and do all sorts of mischief? We judge the minister's statement by the Word of God, and pronounce it true. We judge the young man's conduct by the same rule, and pronounce it false. The matter is quite simple. We have no reason to believe that the unhappy young man ever really tasted the true grace of God; for if he had, he would love and cultivate and exhibit holiness. The Christian has to struggle with sin; but struggling with it and wallowing in it are two totally different ideas. In the one case we can count on Christ's sympathy and grace; in the other, we are actually blaspheming His name by implying that He is the minister of sin.
We consider it a very serious mistake to set about judging the truth of God by the actings of men. All who do so must reach a false conclusion. The true way is just to reverse the order. Get hold of God's truth first, and then judge everything by that. Set up the divine standard, and test everything thereby. Set up the public scales, and weigh every man's load therein. The scales must not be regulated by each man's load, but each man's load be tested by the scales. If ten thousand professors were to fall away, and live and die in open sin, it would not shake our confidence in the divine doctrine of final perseverance. The selfsame Word that proves the doctrine to be true, proves them to be false. "They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us; but they went out, that they might be manifest that they were not all of us." (1 John ii. 19.) "The foundation of God standeth sure, having this seal, The Lord knoweth them that are His. And, let every one that nameth the name of Christ depart from iniquity." (2 Tim. ii. 19.)
III. We shall now proceed to examine the various passages of Scripture which, as you say, are generally adduced by those who seek to overthrow the doctrine of final perseverance. But before doing so, we deem it of importance to lay down the following fundamental principle, which will, in our judgment, be found most helpful in the interpretation of Scripture generally. The principle is very simple. No one passage of Holy Scripture can by any possibility contradict another. If therefore there be a seeming contradiction, it must arise from our want of spiritual intelligence. Thus, for example, if any one were to quote James ii. 24 in defense of the doctrine of justification by works, I might not be able to answer him. It is quite possible that thousands, like Luther, have been sadly perplexed by that passage. They may feel the fullest and clearest assurance that they are justified, and that not by any works that they have done, but simply "by faith of Jesus Christ," and yet be wholly unable to explain these words of James—"Ye see then how that by works a man is justified, and not by faith only."
Now, how is one to meet such a difficulty as this? He really does not understand the apostle James. He is involved in much perplexity by the apparent contradiction between James and Paul. What is he to do? Just to apply the principle above stated. No one passage of Scripture can possibly contradict another. As well might we apprehend a collision between two of the heavenly bodies while moving in their divinely appointed orbits, as that two inspired writers could possibly clash in their statements. Well, then, I read in Rom. iv. 5 such plain words as these: "But to him that worketh not, but believeth on Him that justifieth the ungodly, his faith is counted for righteousness." Here I find works entirely excluded as a ground of justification, and faith alone recognized. So also in chapter iii. I read, "Therefore we conclude that a man is justified by faith without (or apart from) works of law." And, again, "Being justified by faith, we have peace with God." Exactly similar is the teaching in the epistle to the Galatians, where we read such plain words as these: "Knowing that a man is not justified by works of law, but by faith of Jesus Christ, even we (Jews) have believed in Jesus Christ, that we might be justified by faith of Christ, and not by works of law: for by works of law shall no flesh be justified." (Chap. ii. 16.)
In all these passages, and many more which might be quoted, works are sedulously excluded as a ground of justification, and that too in language so plain that a wayfaring man, though a fool, need not err therein. If therefore we cannot explain James ii. 24, we must either deny its inspiration or have recourse to our principle, namely, that no one passage of Holy Scripture can possibly contradict another, and so remain, with unshaken confidence and unruffled repose, rejoicing in the grand foundation truth of justification by faith alone, apart from law-works altogether.
Having called the reader's attention to the famous passage in James ii., it may not be amiss to offer him, in passing, a word or two of exposition which will help him in the understanding of it. There is a little word in verse 14 which will furnish the key to the entire passage. The inspired apostle inquires, "What doth it profit, my brethren, though a man say he hath faith?" Had he said, What doth it profit though a man have faith? the difficulty would be insuperable, the perplexity hopeless. But the important word "say" quite removes all difficulty, and unfolds in the simplest possible way the point which the apostle has in his mind. We might inquire, What doth it profit though a man say he hath ten thousand a year, if he have it not?
Now, we are aware that the word "say" is constantly left out in quoting James ii. 14. Some have even ventured to assert that it is not in the original. But any one who can read Greek has only to look at the passage and he will see the word legee (say) placed there by the Holy Ghost, and left there by all our leading editors and biblical critics; nor can we well conceive a word of more vital importance in a passage. Its influence, we believe, is felt throughout the entire context in which it occurs. There is no use in a man merely saying he has faith; but if he really has it, it "profits" him for time and eternity, inasmuch as it connects him with Christ, and puts him in full and inalienable possession of all that Christ has done and all that He is for us before God.
