The Covenant of Grace
The second covenant, in which God freely offers unto sinners life and salvation by Jesus Christ, requiring of them faith in him. WCF VII.3-6 teaches that the covenant of grace is one in substance through both testaments, differently administered under the law and under the gospel. This is the structural hinge of the Standards' redemptive-historical theology.

Man by his fall having made himself incapable of life by that covenant, the Lord was pleased to make a second, commonly called the covenant of grace: wherein he freely offered unto sinners life and salvation by Jesus Christ, requiring of them faith in him that they may be saved, and promising to give unto all those that are ordained unto life his Holy Spirit, to make them willing and able to believe.
This covenant of grace is frequently set forth in the Scripture by the name of a testament, in reference to the death of Jesus Christ the testator, and to the everlasting inheritance, with all things belonging to it, therein bequeathed.
This covenant was differently administered in the time of the law and in the time of the gospel: under the law it was administered by promises, prophecies, sacrifices, circumcision, the paschal lamb, and other types and ordinances delivered to the people of the Jews, all fore-signifying Christ to come, which were for that time sufficient and efficacious, through the operation of the Spirit, to instruct and build up the elect in faith in the promised Messiah, by whom they had full remission of sins and eternal salvation; and is called the Old Testament.
Under the gospel, when Christ the substance was exhibited, the ordinances in which this covenant is dispensed are the preaching of the Word and the administration of the sacraments of Baptism and the Lord's Supper; which, though fewer in number, and administered with more simplicity and less outward glory, yet in them it is held forth in more fulness, evidence, and spiritual efficacy, to all nations, both Jews and Gentiles; and is called the New Testament. There are not, therefore, two covenants of grace differing in substance, but one and the same under various dispensations.
This perseverance of the saints depends, not upon their own free will, but upon the immutability of the decree of election, flowing from the free and unchangeable love of God the Father; upon the efficacy of the merit and intercession of Jesus Christ; the abiding of the Spirit and of the seed of God within them; and the nature of the covenant of grace: from all which ariseth also the certainty and infallibility thereof.
Sacraments are holy signs and seals of the covenant of grace, immediately instituted by God, to represent Christ and his benefits, and to confirm our interest in him: as also to put a visible difference between those that belong unto the Church and the rest of the world; and solemnly to engage them to the service of God in Christ, according to his Word.
Baptism is a sacrament of the New Testament, ordained by Jesus Christ, not only for the solemn admission of the party baptized into the visible Church, but also to be unto him a sign and seal of the covenant of grace, of his ingrafting into Christ, of regeneration, of remission of sins, and of his giving up unto God, through Jesus Christ, to walk in newness of life: which sacrament is, by Christ's own appointment, to be continued in his Church until the end of the world.
Shorter Catechism
1 question
God having, out of his mere good pleasure, from all eternity, elected some to everlasting life did enter into a covenant of grace, to deliver them out of the estate of sin and misery, and to bring them into an estate of salvation by a Redeemer.

God doth not leave all men to perish in the estate of sin and misery, into which they fell by the breach of the first covenant, commonly called the Covenant of Works; but of his mere love and mercy delivereth his elect out of it, and bringeth them into an estate of salvation by the second covenant, commonly called the Covenant of Grace.
The covenant of grace was made with Christ as the second Adam, and in him with all the elect as his seed.
The grace of God is manifested in the second covenant, in that he freely provideth and offereth to sinners a Mediator, and life and salvation by him; and requiring faith as the condition to interest them in him, promiseth and giveth his Holy Spirit to all his elect, to work in them that faith, with all other saving graces; and to enable them unto all holy obedience, as the evidence of the truth of their faith and thankfulness to God, and as the way which he hath appointed them to salvation.
The covenant of grace was not always administered after the same manner, but the administrations of it under the Old Testament were different from those under the New.
The covenant of grace was administered under the Old Testament, by promises, prophecies, sacrifices, circumcision, the passover, and other types and ordinances, which did all foresignify Christ then to come, and were for that time sufficient to build up the elect in faith in the promised Messiah, by whom they then had full remission of sin, and eternal salvation.
Under the New Testament, when Christ the substance was exhibited, the same covenant of grace was and still is to be administered in the preaching of the word, and the administration of the sacraments of Baptism and the Lord's Supper; in which grace and salvation are held forth in more fulness, evidence, and efficacy, to all nations.
Sum of Saving Knowledge

Head II. The remedy provided in Jesus Christ for the elect by the covenant of Grace §2 →
The sum of the covenant of redemption is this: God having freely chosen to life a certain number of lost mankind, for the glory of his rich grace, did give them, before the world began, to God the Son, appointed Redeemer, that, upon condition he would humble himself so far as to assume the human nature, of a soul and a body, to personal union with his divine nature, and submit himself to the law, as surety for them, and satisfy justice for them, by giving obedience in their name, even to the suffering of the cursed death of the cross, he should ransom and redeem them all from sin and death, and purchase to them righteousness and eternal life, with all saving graces leading thereto, to be effectually, by means of his own appointment, applied in due time to every one of them.
For the accomplishment of this covenant of redemption, and making the elect partakers of the benefits of it in the covenant of grace, Christ Jesus was clad with the threefold office of Prophet, Priest, and King: made a Prophet, to reveal all saving knowledge to his people, and persuade them to believe and obey the same; made a Priest, to offer up himself a sacrifice once for them all, and to intercede continually with the Father, for making their persons and services acceptable to him; and made a King, to subdue them to himself, to feed and rule them by his own appointed ordinances, and to defend them from their enemies.
Head III. The outward means appointed to make the elect partakers of this covenant §3 →
In the word of God preached by sent messengers, the Lord makes offer of grace to all sinners, upon condition of faith in Jesus Christ; and whoever does confess their sin, accept Christ's offering, and submit themselves to his ordinances, he will have them received into the honour and privileges of the covenant of grace. By the ordinances, God will have the covenant sealed for confirming the bargain on the foresaid condition. By the church, he will have them hedged in, and helped forward to the keeping of the covenant. And by prayer, he will have his own glorious grace, promised in the covenant, to be daily drawn forth, acknowledged, and employed.
The covenant of grace, set down in the Old Testament before Christ came, and in the New since he came, is one and the same in substance, albeit different in outward administration.
