Christ as a Prophet administers the Covenant of Grace
This may be taken up in three things,
I. His intimating and offering the covenant to sinners,
by his word, for bringing them personally into it. This he did from the time of
Adam's fall, is now doing, and will do even unto the end of time, that the
mystery of God shall be finished. He began the Old Testament dispensation
thereof, in person. Appearing in human shape, with his own mouth he gave the
first notice of the covenant that ever there was in the world and made the first
offer of it in paradise, Gen. 3:8,15. He carried it on by prophets and ordinary
teachers, whom he commissioned for that effect, and furnished with gifts for
the work. The former of these he employed to write in his name, as well as to
speak therein, in that matter: and by both. he spoke to sinners, intimating and
offering the covenant unto them, by their means; whether through the word
written or spoken. And thus he managed that work, to the salvation of those who
believed, in the patriarchal ages before and after the flood; and all along the
time of the Jewish church, fiom Moses to the end of that dispensation, Then he
also began the New Testament dispensation in his own person. Having by his
incarnation become man, he applied himself to this work. Though he was born king
of the Jews, Matt. 2: 2. and many of them would have had him to have mounted
their throne, John vi, 15.; yet he choosed rather to appear in the character of
a prophet, and betake himself, unto the work of the ministry, for to preach the
gospel, and intimate and offer the covenant to perishing sinners; and so he was
a minister of the circumcision, Rom. 15 : 8 of him in this capacity
particuiarly, Solomon, that king-preacher, was a type, Eccl. 1:1. And this also
he did, and still doth, carry on mediately and by proxy, especially after his
ascension into heaven; and that, partly by his apostles and other extraordinary
officers, whom he employed to write, as well as to speak, in his name; and
partly by ordinary ministers of the gospel, to be continued in the church, to
the end of the world, Eph. 4:11, 12, 13. Thus he is now administering the
covenant unto us, by putting his written word of the Old and New Testaments in
our hands, and sending men in his name to preach the gospel unto us. By these
means he speaks tn sinners intimating and offering them the covenant: and so he
carries on the work, to the salvation of those that believe, and rendering
unbelievers inexcusable, 2 Cor. 5:20.; Rev. 3:22. ; Luke10:16. Wherefore the
offer of the covenant, made to us in the gospel, is his offer: and though the
word is sent to us by men, they are but his voice in the matter, he is the
speaker. Then "see that ye refuse not him that speaketh," Heb. 12:
25.
2. His making the intimation and offer of the covenant
effectual to the elect, by the Spirit: I Pet. 1:12. 'By them that have preached
the gospel unto you, with the Holy Ghost sent down from heaven.' The great
Prophet of the covenant can effectually teach the most unteachable sinners of
mankind; causing light not only to break forth in a dark world, by his word, but
in dark hearts, by his Spirit: for the fulness of the Spirit of light is in
him, and he hath eye-salve for the spiritually blind, Rev. 3:18. He knoweth
who are his, in whose name he contracted with the Father, and received the
promise of the Spirit: and sooner or later, he so enlightens them, that he
rescues them from under the power of their spiritual darkness, and renders the
administration of the covenant effectual to them, however ineffectual it be to
others, Col. i. 13. And this he doth by bringing his word to them with power:
through the efficacy of his Spirit opening their eyes. In the first place, by
his Spirit acting upon them as a Spirit of bondage, he sets home on their
consciences, the holy law in the commands and curse thereof, as of divine
authority, and binding on them in particular. Hereby they are convinced of
their sin and misery, seeing their sin as heinous in the sight of God, and his
wrath due to them for their sin: they are filled with remorse, terror, and
anxiety; are made to pant for relief, feel an absolute need of Christ and his
righteousness, and despair of relief by any other way, Acts 2:37. and 16:29,
30. And then, by the same Spirit acting within them, as a Spirit of life, and
communicated unto them from himself, in the word of the gospel, he sets home on
their hearts and consciences, the glorious gospel in its free promise of life
and salvation to sinners through Jesus Christ, as it stands in the holy
scriptures clearing and demonstrating the same unto them, to be the infallible
word of the eternal God, and his word to them in particular: 2Thess. 2:13. 'Ye
received it not as the word of men, but (as it is: in truth) the word of God.'
Chap. 1:5. "For our gospel came not unto you in word only, but also in
power, and in the: Holy Ghost, and in much assurance." This demonstration
of the Spirit is that which immediately cleareth to them the ground of their
believing in particular; as saith the apostle, 1 Cor. 2:4, 5. "My
preaching was in demonstration of the Spirit, and of power : that your faith
should not stand in the wisdom of men, but in the power of God." And it
is an internal attestation of the word of the gospel unto them, distinct from
the clearest external or ministerial attestation of it; according to the saying
of our Saviour, John 15:26 "The Spirit of truth, which proceedeth from the
Father, he shall testify of me ;' ver. 27. "And ye also shall bear
witness." By the power hereof, getting, by way of spiritual sight, John
6:40. a knowledge of Christ in his transcendent glory and excellency,
exhibited to them in the free promise of the gospel, they are infallibly
brought to believe. The Spirit thus applying the word of the gospel to them,
they greedily embrace it, and apply it to themselves by faith; as may be seen
in these converts, Acts 2:38. "Then Peter said unto them, Repent, and be
baptized every one of you in the name of Jesus Christ, for the remission of
sins;" ver. 39. " For the promise is unto you ;" ver. 41. "Then
they that gladly received his word, were baptized."
Lastly, His teaching and instructing them by his word and
Spirit, from thenceforth, as children of the covenant, his own disciples. The
whole plan of salvation is laid down in the covenant, being a mystery of the
manifold wisdom of God, whereof there is still more and more to be learned: and
Christ is the great Prophet; to teach it. And "the secret of the Lord is
with them that fear him ; and he will shew them his covenant," Psal. 25:14.
The saints, by reason of the remains of darkness in their minds while here,
are apt to lose sight of the parties in the covenant: but the great Prophet is
to shew them the Father, and to manifest himself unto them, by the Spirit. The
condition of the covenant, the Mediator's own righteousness, the sole ground of
all their hopes, cannot be kept in view, but by means of the light of life from
himself. And in his light only can they have a believing view of the promises
and privileges of the covenant. The duties of the covenant, whereof the
exceeding broad law of the ten commandments is the rule, are many ; and though
they be clear in themselves, yet, are they often so dark and perplexed to us,
that we cannot distinguish between sin and duty: but the children of the
covenant have an infallible Teacher, whom they may consult in all cases, and of
whom they may learn how to steer their course in every point; and "the meek
will he guide in judgment, the meek will he teach his way," Psal. 25:9.
The darkness brought on mankind by sin, nothing but the grace of the new
covenant can effectually dispel. The true light is a benefit of that covenant,
purchased by the blood of Christ and lodged with him among the rest of the
benefits of his great trust: and he hath the dispensing of it, as the great
Prophet of the covenant. To him then must we have our recourse for light in all
cases, whether we be under the midnight-darkness of a natural state, or under
the twilight-darkness of the present imperfection of a state of grace ; yea, in
the mid-day light of glory, the Lamb is the light of the heavenly city, Rev.
21:23.
