O christian, as ever thou wouldst walk with God in comfortable communion with him, study and exercise this life of faith, in the daily use and improvement of Christ, who is our life, and hope, and all.

To believe in the Holy Ghost, and live upon his grace.

Grand Direct. III. Understand well what it is to believe in the Holy Ghost; and see that he dwell and operate in thee, as the life of thy soul, and that thou do not resist or quench the Spirit, but thankfully obey him.

Each person in the Trinity is so believed in by christians, as that in baptism they enter distinctly into covenant with them: which is, to accept the mercies of, and perform the duties to, each person distinctly.[88] As to take God for our God is more than to believe that there is a God, and to take Christ for our Saviour is more than barely to believe that he is the Messiah; so to believe in the Holy Ghost, is to take him for Christ's agent or advocate with our souls, and for our Guide, and Sanctifier, and Comforter, and not only to believe that he is the third person in the Trinity. This therefore is a most practical article of our belief.

If the blasphemy against the Holy Ghost be the unpardonable sin, then all sin against the Holy Ghost must needs have a special aggravation by being such. And if the sin against the Holy Ghost be the greatest sin, then our duty towards the Holy Ghost is certainly none of our smallest duties. Therefore the doctrine of the Holy Spirit, and our duty towards him, and sin against him, deserve not the least or last place in teaching, learning, and most serious consideration.

Two sorts do most dangerously sin against or abuse the Holy Ghost. The first is the profane, who through custom and education can say, "I believe in the Holy Ghost," and say, that "he sanctifieth them and all the elect people of God;" but hate or resist all sanctifying works and motions of the Holy Ghost, and hate all those that are sanctified by him, and make them the objects of their scorn, and deride the very name of sanctification, or at least the thing.[89]

The second sort are the enthusiasts, or true fanatics, who advance, extol, and plead for the Spirit, against the Spirit; covering their greatest sins against the Holy Ghost, by crying up, and pretending to the Holy Ghost.[90] They plead the Spirit in themselves against the Spirit in their brethren, yea, and in almost all the church: they plead the authority of the Spirit in them, against the authority of the Spirit in the holy Scriptures; and against particular truths of Scripture; and against several great and needful duties which the Spirit hath required in the word; and against the Spirit in their most judicious, godly, faithful teachers. But can it be the Spirit that speaks against the Spirit? Is the Spirit of God against itself? Are we "not all baptized by one Spirit (and not divers or contrary) into one body?" 1 Cor. xii. 12, 13. But it is "no marvel, for Satan to be transformed into an angel of light, or his ministers into the ministers of Christ, and of righteousness, whose end shall be according to their works," 2 Cor. xi. 13-15. The Spirit himself therefore hath commanded us, that we "believe not every spirit, but try the spirits whether they be of God; because many false prophets are gone out into the world," 1 John iv. 1. "Yea, the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils," 1 Tim. iv. 1. Therefore take heed that you neither mistake nor abuse the Holy Spirit.

1. The doctrine concerning the Holy Ghost, to be believed, is briefly this: (1.) That the Holy Ghost, as given since the ascension of Christ, is his agent on earth, or his advocate with men (called by him the Paraclete): instead of his bodily presence, which for a little space he vouchsafed to a few, being ascended, he sendeth the Holy Spirit as better for them, to be his agent continually to the end, and unto all, and in all that do believe, John xvi. 7, 8. (2.) This Holy Spirit, so sent, infallibly inspired the holy apostles and evangelists, first to preach, and then to write the doctrine of Christ, contained (as indited by him) in the holy Scriptures; perfectly imprinting therein the holy image of God, John xv. 26; xvi. 13; Gal. iii. 1-4; Heb. ii. 3, 4. (3.) The same Spirit in them, sealed this holy doctrine, and the testimony of these holy men, by many miracles and wonderful gifts, by which they did actually convince the unbelieving world, and plant the churches. (4.) The same Spirit (having first by the apostles given a law or canon to the universal church, constituting its offices and the duty of the officers, and the manner of their entrance) doth qualify and dispose men for the stated, ordinary ministerial work, (which is to explain and apply the foresaid Scriptures,) and directeth those that are to ordain and choose them (they being not wanting on their part); and so he appointeth pastors to the church, Eph. iii. 2-4, 8, 13. (5.) The same Spirit assisteth the ministers (thus sent in their faithful use of the means) to teach and apply the holy Scriptures according to the necessities of the people, the weight of the matter, and the majesty of the word of God. (6.) The same Spirit doth by this word (heard or read) renew and sanctify the souls of the elect; illuminating their minds, opening and quickening their hearts, prevailing with, changing, and resolving their wills, thus writing God's word, and imprinting his image by his word upon their hearts, making it powerful to conquer and cast out their strongest, sweetest, dearest sins, and bringing them to the saving knowledge, love, and obedience of God in Jesus Christ, Acts xxvi. 18; John xiv. 16, 26. (7.) The same Holy Spirit assisteth the sanctified in the exercise of this grace, to the increase of it, by blessing and concurring with the means appointed by him to that end: and helpeth them to use those means, perform those duties, conquer temptations, oppositions, and difficulties, and so confirmeth and preserveth them to the end. (8.) The same Spirit helpeth believers, in the exercise of grace, to feel it, and discern the sincerity of it in themselves, in that measure as they are meet for, and in those seasons when it is fittest for them. (9.) The same Spirit helpeth them hereupon to conclude that they are justified and reconciled to God, and have right to all the benefits of his covenant. (10.) Also, he assisteth them actually to rejoice in the discerning of this conclusion. For though reason of itself may do something in these acts, yet so averse is man to all that is holy, and so many are the difficulties and hinderances in the way, that to the effectual performance, the help of the Spirit of God is necessary.

By this enumeration of the Spirit's operations, you may see the errors of many detected, and many common questions answered. 1. You may see their blindness, that pretend the Spirit within them, against Scripture, ministry, or the use of God's appointed means: when the same Spirit first indited the Scripture, and maketh it the instrument to illuminate and sanctify our souls. God's image is, (1.) Primarily, in Jesus Christ his Son. (2.) Derivatively, by his Spirit, imprinted perfectly in the Holy Scriptures. (3.) And by the Scripture, or the holy doctrine of it, instrumentally impressed on the soul. So that the image of God in Christ, is the cause of his image in his holy word or doctrine, and his image in his word, is the cause of his image on the heart. So a king may have his image, (1.) Naturally, on his son, who is like his father. (2.) Expressively, in his laws, which express his wisdom, clemency, and justice. (3.) And effectively, on his subjects and servants, who are by his laws reduced to a conformity to his mind. As a man may first cut his arms or image on his seal, and then by that seal imprint it on the wax; and though it be perfectly cut on the seal, it may be imperfectly printed on the wax; so God's image is naturally perfect in his Son, and regularly or expressively perfect on the seal of his holy doctrine and laws; but imperfectly on his subjects, according to their reception of it in their several degrees.

Therefore it is easy to discern their error, that tell men the light or Spirit within them, is their rule, and a perfect rule, yea, and that it is thus in all men in the world; when God's word and experience flatly contradict it, telling us that infidels and enemies of God, and all the ungodly, are in darkness, and not in the light; and that all that speak not according to this word, (the law and testimony,) have "no light in them;" and therefore no "perfect light to be their rule," Isa. viii. 20. The ministry is sent, to bring them from darkness to light: therefore, they had not a sufficient light in them before, Acts xxvi. 17, 18. "Woe to them that put darkness for light, and light for darkness!" Isa. v. 20: telling the children of darkness, and the haters of the light, that they have a perfect light and rule within them, when God saith, "They have no light in them." See 1 John i. 4-8. "He that saith he is in the light, and hateth his brother, is in darkness even till now," 1 John ii. 9-11. The light within a wicked man, is "darkness" and "blindness," and therefore not his rule, Matt. vi. 23; Eph. v. 8. Even the light that is in godly men, is the knowledge of the rule, and not the rule itself at all, nor ever called so by God. Our rule is perfect; our knowledge is imperfect: for Paul himself saith, "We know in part; but when that which is perfect is come, then that which is in part shall be done away: now we see through a glass darkly," 1 Cor. xiii. 9, 10, 12. "The gospel is hid to them that are lost," being "blinded by Satan," 2 Cor. iv. 3, 4.
