But in addition to all that has been advanced in reference to this question, we cannot but think that the occurrence of the clause, "who walk not after the flesh, but after the Spirit," in verse 4, affords abundant evidence of its misplacement in verse 1. We cannot, for a moment, admit the thought of redundancy in holy Scripture. Now, in verse 4 it _is_ a question of walk--a question of our fulfilling "the righteousness [mark the word--δικαίωμα] of the law," and hence the clause is in its right, because divinely fitted, place. A person who walks in the Spirit--as every Christian ought--fulfills the righteousness of the law. Love is the fulfilling of the law; and love will lead us to do what the ten commandments could never effect, namely, to love our enemies. No lover of holiness, no advocate of practical righteousness, need ever be the least afraid of losing aught by abandoning the legal ground, and taking his place on the elevated platform of true Christianity--by turning from Mount Sinai to Mount Zion--by passing from Moses to Christ. No; he only reaches a higher source, a deeper spring, a wider sphere of holiness, righteousness, and practical obedience.
And then, if any one should feel disposed to ask, Does not the line of argument which we have been pursuing tend to rob the law of its characteristic glory? We reply, Most assuredly not. So far from this, the law was never so magnified, never so vindicated, never so established, never so glorified, as by that precious work which forms the imperishable foundation of all the privileges, the blessings, the dignities, and the glories of Christianity. The blessed apostle anticipates and answers this very question in the earlier part of his epistle to the Romans. "Do we then," he says, "make void the law through faith? Far be the thought; yea, we establish the law." How could the law be more gloriously vindicated, honored, and magnified than in the life and death of the Lord Jesus Christ? Will any one seek, for a moment, to maintain the extravagant notion that it is magnifying the law to put Christians under it? We fondly trust the reader will not. Ah! no; all this line of things must be completely abandoned by those whose privilege it is to walk in the light of the new creation; who know Christ as their life and Christ as their righteousness, Christ their sanctification, Christ their great exemplar, Christ their model, Christ their all and in all; who find their motive for obedience, not in the fear of the curses of a broken law, but in the love of Christ, according to those exquisitely beautiful words, "The love of Christ"--not the law of Moses--"constraineth us; because we thus judge, that if one died for all, then were all dead. And He died for all, that they which live should not henceforth live unto themselves, but unto Him which died for them and rose again." (2 Cor. v.)
Could the law ever produce aught like this? Impossible. But, blessed forever be the God of all grace, "what the law could not do," not because it was not holy, just, and good, but "in that it was weak through the flesh"--the workman was all right, but the material was rotten, and nothing could be made of it; but "God sending His own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh, that the righteousness of the law might be fulfilled in us, who," as risen with Christ, linked with Him by the Holy Ghost, in the power of a new and everlasting life, "walk not after the flesh, but after the Spirit."
This, and only this, is true, practical Christianity; and if the reader will turn to the second of Galatians, he will find another of those fine, glowing utterances of the blessed apostle, setting forth, with divine force and fullness, the special glory of Christian life and walk. It is in connection with his faithful rebuke of the apostle Peter at Antioch, when that beloved and honored servant of Christ, through his characteristic weakness, had been led to step down, for a moment, from the elevated moral ground on which the gospel of the grace of God places the soul. We cannot do better than quote the entire paragraph for the reader: every sentence of it is pregnant with spiritual power.
