Our Saviour frequently rebuked those who trusted in themselves that they were righteous, and despised others. This self-righteous temper prevailed in the sect of the Pharisees; and Paul, who was a Pharisee, was obliged to renounce it, when he became a follower of Christ. He then prayed to be found, not having his own righteousness, but the righteousness which is of God by faith. In his strong desire and earnest prayer for the salvation of his countrymen, the Jews, he regarded it as their great and fatal error, that, "being ignorant of God's righteousness, they went about to establish their own righteousness."
Self-righteousness is offensive to God. The king, in the parable, was displeased, because one of the guests appeared at the marriage, not having on a wedding garment. But when we array ourselves in our own righteousness of filthy rags, and present ourselves in the assembly of the saints, before the God of holiness, and claim his approbation and smile, because we are thus arrayed, we offer insult to the King Supreme. We evince that we have no right appreciation of his holiness and justice: and while we profess to honor him as God, we so degrade his moral perfections as to make him altogether such an one as ourselves. This temper of mind rejects the mediation and righteousness of Christ, and thereby sets at nought the counsel of God, in the great scheme of salvation. The Father is well pleased with the Son, for his righteousness' sake; and he cannot be well pleased with those who despise that righteousness, and choose to appear in their own.
Self-righteousness is ruinous to the soul. It may be highly esteemed among men; for the Pharisees, who loved the praise of men more than the praise of God, obtained their reward, in being honored for their great sanctity. But God searches the heart, and in his view the outward sanctity avails nothing, while all within is rottenness. Yet the disguise cheats mankind, and cheats him who wears it. Blindly and stupidly trusting to his own righteousness, he is at ease, and cries Peace, Peace, until sudden destruction comes upon him. It is one of Satan's most successful artifices, to lull men to sleep in their own righteousness. Many who have been alarmed by a view of their outward sins, have reformed their lives; and, relying on their morality, have, without any heart-religion, without any true faith in Christ, fatally dreamed their life away in the vain hope that all will be well at last. So difficult is it to rouse men from this delusion, that publicans and harlots entered into the kingdom of heaven before the self-righteous Pharisees.
The doctrine of grace is the remedy for self-righteousness. It is a remedy which the unholy heart greatly dislikes, but if once received, it proves an effectual antidote to the evil. It slays all self-dependence, and lays the guilty sinner prostrate at the feet of mercy. He turns from his own righteousness, as from his sins, with loathing and abhorrence, and pleads, and trusts, and hopes for mercy only for the sake of Christ. In this method of salvation there is not compromise with the self-righteous spirit; no reliance is admitted either on absolute merit, or on comparative merit. Every one is required to come to Christ, as most guilty and vile, and to seek mercy as the chief of sinners. He must bring no plea that he is more worthy, or less worthy than his neighbor. So long as he relies on such a plea, the door of mercy is shut against him. He is taught to receive salvation as a free gift, absolutely free, without money and without price.
The doctrine of grace completely excludes all human boasting. This was Paul's view of it. "Where is boasting then? It is excluded. By what law? Works? Nay, but by the law of faith." Its tendency to humble men before God, and teach them to glory in the Lord alone, is an excellence which the inspired apostle highly prized. This endeared the doctrine to him, and should endear it to us. We are prone to think of ourselves above what we ought to think: but we have the means at hand for humbling our pride, in the interrogatory, "Who made thee to differ from another? and what hast thou, that thou didst not receive?"
This doctrine presents the strongest motive to holiness. It has been charged against it, that it leads to licentiousness; and this charge is as old as the days of the apostles. It was then asked, "Shall we continue in sin, that grace may abound?" and it was falsely asserted that they taught, "Let us do evil, that good may come." If, in advocating this doctrine, we meet with similar charges, we may rejoice in the proof thus furnished, that we stand on apostolic ground. But the whole charge is without foundation. Men may be self-righteous Pharisees, and, at the same time, live in sin; but when self-righteousness is destroyed by the Spirit of grace, the man becomes dead, not only to the law, but also to sin, and, being dead to sin, he can live no longer therein. Men may, in a self-righteous spirit, abstain from sin, while they love it. But the doctrine of grace, when received into the heart, destroys the very love of sin. A sense of obligation for free and unmerited mercy, occupies the heart, and constrains to holy obedience.
This doctrine is honorable to God. All flesh is humbled before him, and he alone is exalted. The cross of Christ is elevated; and men are attracted to it, and taught to glory in it alone. The full salvation, as it comes forth from the triune God, in its completeness, and perfect adaptedness to our wretched and lost condition, becomes the object of our admiring delight, and calls forth our joyful ascriptions of praise.
This doctrine unites the people of God. All come to Christ on the same level. The rich, the poor, the learned, the unlearned, the bond, the free; all come to him, without distinction of rank, or of merit. All melt before him into penitence and love, and their hearts become one. Under the full influence of this doctrine, no man can glory in men, or treat with contempt a fellow member of Christ, a weak brother whom Christ has received.
This doctrine prepares us to join the song of the redeemed in heaven. Even here we learn to sing, "Not unto us, not unto us, but unto thy name give glory." And the same shall be our song, when we stand before the throne. "Salvation, and glory, and honor, and power, unto the Lord our God." The celestial harps cannot sound a self-righteous note, It would disturb the heavenly harmony. Every heart feels, and every song declares, that "Salvation is of the Lord."
