“ALTHOUGH true believers be not under the law as a covenant of works, to be thereby justified or condemned, yet is it of great use to them, as well as others in that as a rule of life, informing them of the will of God and their duty; it directs and binds them to walk accordingly; discovering the sinful pollutions of their nature, hearts and lives; so as, examining themselves thereby, they may come to further conviction of, humiliation for, and hatred against sin; together with a clearer sight of the need they have of Christ, and the perfection of His obedience. It is likewise of use to the regenerate, to restrain their corruptions, in that it forbids sin; and the threatenings of it serve to show what even their sins deserve, and what afflictions in this life they may expect for them, although freed from the curse thereof threatened in the law. The promises of it, in like manner show them God’s approbation of obedience, and what blessings they may expect upon the performance thereof, although not due to them by the law as a covenant of works: so as to a man’s doing good, and refraining from evil, because the law encourageth to the one, and deterroth from the other, is no evidence of his being under the law, and not under grace” (chap. xix. sec. 6).
“Neither are the forementioned uses of the law contrary to the grace of the gospel, but do sweetly comply with it; the Spirit of Christ subduing and enabling the will of man to do that freely and cheerfully which the will of God revealed in the law requireth to be done” (Confession of Faith, chap. xix. sec. 7).
