The following is a quote from Thomas Boston, a man involved in the “Marrow” controversy, on sanctification. This quote is fitting in light of the recent controversy on sanctification. It is rather strange that people are trying to lump Tullian Tchividjian with the” Marrow” men. The following quote would seem to be something that Tullian would seem uncomfortable with – exhorting believers to holiness with the use of the Law and also with threats.
This double seal answers to the two parts of the covenant; Jer. 32:40, “And I will make an everlasting covenant with them, that I will not turn away from them to do them good; but I will put my fear in their hearts, that they shall not depart from me.” This covenant shall not fail on God’s part, for it hath this seal, the Lord knoweth them that are his;” nor on the part of the saints, for it hath this seal, “Let every one that nameth the name of Christ depart from iniquity.” Let us attend,
1. To the seal itself, which, in its general nature, is a command of sanctification; in which consider, to whom it is directed, upon whom this awful charge is laid. They are the Lord’s own words, directed to every one that nameth the name of his Son, that is, to all who profess Christ. And this character of professors serves not only to distinguish them from those without the church, who are incapable of apostacy; but also shows the obligation laid on them to holiness by their profession, the holy name named by them binding them to a holy life. The inconsistency between the holy profession and an unholy life, which, though men join together, God will have separated, sooner or later, for he will strip them either of their fair name, or their foul heart and life, in time or in eternity. Consider, the duty commanded, “to depart from iniquity,” as from a thing one formerly stood to and followed. Iniquity is that thing which we all naturally follow as a master and leader; but there must be a falling off from it, an apostacy, or falling away from sin, as the word imports. And this is the way to prevent apostacy from the Lord; for this does import, that it is some one iniquity or other indulged, and left to reign in the heart, which betrays professors into apostacy, as Judas, Demas, &c. Consider,
2. How this can be a seal to secure the saints and elect ones from apostacy, since it is but a commandment? To this I answer, that the nature of the preceding seal would seem to have required this expression, “And they that are his depart from iniquity.” But it is in form of a command, to show that the saints depart from iniquity by choice, and that they are by the Lord himself powerfully determined to this choice; so that their perseverance is both rational and gracious. It is a command, at the same time it is a powerful and efficacious command of God, like that in Gen. 1:3, “And God said, Let there be light, and there was light;” a command which effects what it requires in all who are his. It is such a command as that in Num. 16:26, (quoted above), which brought away from the tents of Dathan and Abiram, all who were not to be swallowed up with them. And this command is going through wherever the gospel is preached, and will go till the last day; like a brisk wind separating the corn from the chaff, carrying away from the tents of sin all who are ordained to eternal life, though others dwell on in them still. Thus, though the profane and hypocritical, and all who are not the Lord’s, are still held by some one bond of sin or other which is never broken: yet this powerful word looses the bands of all sin, sets them and their sins asunder, and keeps them asunder, who, being sealed with the first seal, are his. And all this God’s efficacious word can do, as well as keep the world from returning into its primitive mass of confusion; Heb. 1:3, “Upholding all things by the word of his power.” And so it is a seal securing them from apostasy.”*
