39 Gal. 3:1, 3; Heb. 6:6
Gal. 3:1, 3

Gal. 3:1 O foolish Galatians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you?

Gal. 3:3 Are ye so foolish? having begun in the Spirit, are ye now made perfect by the flesh?

Heb. 6:6

If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.

God gave to Adam a law, as a covenant of works, by which he bound him and all his posterity to personal, entire, exact, and perpetual obedience; promised life upon the fulfilling, and threatened death upon the breach of it; and endued him with power and ability to keep it.

This law, after his fall, continued to be a perfect rule of righteousness; and, as such, was delivered by God upon mount Sinai in ten commandments, and written in two tables; the first four commandments containing our duty towards God, and the other six our duty to man.

Beside this law, commonly called moral, God was pleased to give to the people of Israel, as a Church under age, ceremonial laws, containing several typical ordinances, partly of worship, prefiguring Christ, his graces, actions, sufferings, and benefits; and partly holding forth divers instructions of moral duties. All which ceremonial laws are now abrogated under the New Testament.

The moral law doth forever bind all, as well justified persons as others, to the obedience thereof; and that not only in regard of the matter contained in it, but also in respect of the authority of God the Creator who gave it. Neither doth Christ in the gospel any way dissolve, but much strengthen, this obligation.

XIX.6 Although true believers be not under the law as a covenant of works, to be thereby justified or …

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 to 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 also 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 as due to them by the law as a covenant of works: so as a man's doing good, and refraining from evil, because the law encourageth to the one, and deterreth from the other, is no evidence of his being under the law, and not under grace.

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.

The light of nature showeth that there is a God, who hath lordship and sovereignty over all; is good, and doeth good unto all; and is therefore to be feared, loved, praised, called upon, trusted in, and served with all the heart, and with all the soul, and with all the might. But the acceptable way of worshipping the true God is instituted by himself, and so limited to his own revealed will, that he may not be worshipped according to the imaginations and devices of men, or the suggestions of Satan, under any visible representations or any other way not prescribed in the Holy Scripture.

Prayer with thanksgiving, being one special part of religious worship, is by God required of all men; and that it may be accepted, it is to be made in the name of the Son, by the help of his Spirit, according to his will, with understanding, reverence, humility, fervency, faith, love, and perseverance; and, if vocal, in a known tongue.

The reading of the Scriptures with godly fear; the sound preaching; and conscionable hearing of the Word, in obedience unto God with understanding, faith, and reverence; singing of Psalms with grace in the heart; as, also, the due administration and worthy receiving of the sacraments instituted by Christ; are all parts of the ordinary religious worship of God: besides religious oaths, vows, solemn fastings, and thanksgivings upon several occasions; which are, in their several times and seasons, to be used in an holy and religious manner.
